Afghan policewoman shoots dead NATO adviser

KABUL: A female Afghan police officer on Monday shot dead a foreign civilian adviser in Kabul police headquarters, officials said, in the first "insider" attack to be carried out by a woman.

It is the latest in a series of insider attacks that have seriously undermined trust between NATO forces and their Afghan allies in the fight against hardline Islamist Taliban insurgents.

An ISAF spokesman said the victim, a civilian adviser, died of his wounds and the female police officer who shot him had been detained.

Interior ministry spokesman Sediq Seidiqqi, confirmed the incident and said an investigation was under way.

A senior security official speaking to AFP anonymously said the victim was a male adviser from NATO and the incident took place at Kabul police headquarters.

The officer was arrested by her other colleagues after the shooting, the official said.

The Afghan conflict has seen a surge in insider attacks this year, with more than 50 of NATO's International Security Assistance Force (ISAF) troops killed by their colleagues in the Afghan army and police.

Pictures: Fungi Get Into the Holiday Spirit

Photograph courtesy Stephanie Mounaud, J. Craig Venter Institute

Mounaud combined different fungi to create a Santa hat and spell out a holiday message.

Different fungal grow at different rates, so Mounaud's artwork rarely lasts for long. There's only a short window of time when they actually look like what they're suppose to.

"You do have to keep that in perspective when you're making these creations," she said.

For example, the A. flavus fungi that she used to write this message from Santa grows very quickly. "The next day, after looking at this plate, it didn't say 'Ho Ho Ho.' It said 'blah blah blah,'" Mounaud said.

The message also eventually turned green, which was the color she was initially after. "It was a really nice green, which is what I was hoping for. But yellow will do," she said.

The hat was particularly challenging. The fungus used to create it "was troubling because at different temperatures it grows differently. The pigment in this one forms at room temperature but this type of growth needed higher temperatures," Mounaud said.

Not all fungus will grow nicely together. For example, in the hat, "N. fischeri [the brim and ball] did not want to play nice with the P. marneffei [red part of hat] ... so they remained slightly separated."

Get 'em While You Can? Gun Sales Soar

The National Rifle Association may still get its way and defeat the lawmakers calling for a ban on the sale of assault ridles, but some gun store owners say it seems their customers aren't taking any chances.

"We have never seen anything like this," said Larry Hyatt, who owns a gun shop in Charlotte, N.C. "We have the Christmas business, the hunting season business, and now we have the political business.

"We have seen a lot of things, but we have never seen anything like this, this is probably four times bigger than the last time we saw a big rush," he said.

Some of the customers in his store said it is the talk of stricter gun control in the wake of the shooting at the Sandy Hook Elementary School in Newtown, Conn., that is driving the rush.

"The way they are trying to approach it, they are just making people who have never thought about buying a gun, now they want to come in here and buy a gun," one customer said.

At NOVA Firearms in Falls Church, Va., there have been "skyrocketing" sales following the Newtown shooting, chief firearms instructor Chuck Nesby said.

"They've been off the charts. Absolutely skyrocketing," Nesby said. "If I could give an award to President Obama and Senator Feinstein would be sales persons of the year."

He was referring to Sen. Dianne Feinstein, D-Calif., who said she will introduce an assault weapons ban in January.

Sales are up 400 percent, he said.

"We're completely out of the so-called assault weapons, semi automatic firearms that are rifles," Nesby said. "Forty percent of those sales went to women and senior citizens. We can't get them now. Everybody, nationwide is out of them the sales have just been off the charts nationwide."

National Rifle Association News Conference Interrupted by Protesters Watch Video

The horrific shooting, when 20-year-old Adam Lanza broke in to the elementary school and killed 20 children and six adults with a semi-automatic rifle, has even some former NRA supporters saying it's time to change the rules on assault weapons.

Those guns were banned from 1994 until 2004, when the ban expired and was not renewed.

Now it's not just lawmakers who have traditionally advocated stricter gun control talking about the need to act.

Republican Sen. Kay Bailey Hutchison of Texas suggested today on CBS' "Face the Nation" that new regulation should be considered.

"We ought to be looking at where the real danger is, like those large clips, I think that does need to be looked at," Hutchison said. "It's the semi-automatics and those large magazines that can be fired off very quickly. You do have to pull the trigger each time, but it's very quick."

Virginia Sen. Mark Warner, a Democrat but a long-time opponent of gun control who like Hutchison has received an A rating from the NRA, has also come out in support of strengthening gun laws.

NRA chief Wayne LaPierre said Friday that more gun control is not the way to stop such shooting from happening again: the answer is more guns, in the form of armed guards in every school.

After being criticized for two days for the proposal, LaPierre today stuck by his guns.

"If it's crazy to call for putting police and armed security in our schools to protect our children, then call me crazy," he said on NBC's "Meet the Press."

"When that horrible monster tried to shoot his way into Sandy Hook school, that if a good guy with a gun had been there, he might have been able to stop [it]," LaPierre said.

LaPierre and the NRA said that the media, the entertainment culture and lack of proper mental health care are to blame, not the proliferation of guns in the United States.

Asa Hutchinson, the former congressman who will lead the effort by the NRA to place armed security guards in schools across the country, said today on "This Week" that gun control efforts would not be part of the "ultimate solution" to gun violence.

S.Korea sheds some Christmas light on North

SEOUL: South Korean church groups have displayed Christmas lights near the tense border with North Korea, an official said on Sunday, despite concerns about a violent response from Pyongyang.

Dozens of church leaders and followers put up the giant display -- featuring thousands of glittering light bulbs on a tree-shaped steel tower -- near the heavily-fortified border on Saturday, a defence ministry spokesman told AFP.

The lights on a military-controlled hill in Gimpo, west of Seoul, will be displayed until early January and can apparently be seen several kilometres away in the impoverished North suffering from chronic power shortage.

Before the South's "Sunshine Policy" of engagement with North Korea launched in 1998, the seasonal lighting displays were common.

Pyongyang repeatedly condemned them as "psychological warfare" by its capitalist neighbour aimed at spreading Christianity in the isolated communist state.

In 2004 the two Koreas agreed to halt official-level cross-border propaganda and the South stopped the Christmas border illuminations completely.

They were resumed in 2010 after North Korea shelled a frontline island, but were postponed last year in a conciliatory gesture following the death of North Korean leader Kim Jong-Il.

But the latest illumination has provoked fear among some local residents who staged a protest amid concerns about potential retaliation from the North, according to Yonhap news agency.

"All residents here are left to tremble in fear... as long as the light tower stays here," a group of residents said in a statement.

Before Kim's death Pyongyang warned of "unexpected consequences" if Seoul displayed Christmas lights in 2011 and vowed unspecified retaliation.

Cross-border tensions have been high since the nuclear-armed North this month staged a long-range rocket launch widely condemned as a disguised ballistic missile test by the international community.

Obama, Congress Waving Bye-Bye Lower Taxes?

The first family arrived in the president's idyllic home state of Hawaii early today to celebrate the holidays, but President Obama, who along with Michelle will pay tribute Sunday to the late Sen. Daniel Inouye at the National Memorial Cemetery of the Pacific, could be returning home to Washington sooner than he expected.

That's because the President didn't get his Christmas wish: a deal with Congress on the looming fiscal cliff.

Members of Congress streamed out of the Capitol Friday night with no agreement to avert the fiscal cliff -- a massive package of mandatory tax increases and federal spending cuts triggered if no deal is worked out to cut the deficit. Congress is expected to be back in session by Thursday.

It's unclear when President Obama may return from Hawaii. His limited vacation time will not be without updates on continuing talks. Staff members for both sides are expected to exchange emails and phone calls over the next couple of days.

Meanwhile, Speaker of the House John Boehner is home in Ohio. He recorded the weekly GOP address before leaving Washington, stressing the president's role in the failure to reach an agreement on the cliff.

"What the president has offered so far simply won't do anything to solve our spending problem and begin to address our nation's crippling debt," he said in the recorded address, "The House has done its part to avert this entire fiscal cliff. ... The events of the past week make it clearer than ever that these measures reflect the will of the House."

Senate Minority Leader Mitch McConnell echoed the sentiment while lamenting the failure to reach a compromise.

"I'm stuck here in Washington trying to prevent my fellow Kentuckians having to shell out more money to Uncle Sam next year," he said.

McConnell is also traveling to Hawaii to attend the Inouye service Sunday.

If the White House and Congress cannot reach a deficit-cutting budget agreement by year's end, by law the across-the-board tax hikes and spending cuts -- the so called fiscal cliff -- will go into effect. Many economists say that will likely send the economy into a new recession.

Reports today shed light on how negotiations fell apart behind closed doors. The Wall Street Journal, citing unnamed sources, reported that when Boehner expressed his opposition to tax rate increases, the president allegedly responded, "You are asking me to accept Mitt Romney's tax plan. Why would I do that?"

The icy exchange continued when, in reference to Boehner's offer to secure $800 billion in revenue by limiting deductions, the speaker reportedly implored the president, "What do I get?"

The president's alleged response: "You get nothing. I get that for free."

The account is perhaps the most thorough and hostile released about the series of unsuccessful talks Obama and Boehner have had in an effort to reach an agreement about the cliff.

Unable to agree to a "big deal" on taxes and entitlements, the president is now reportedly hoping to reach a "small deal" with Republicans to avoid the fiscal cliff.

Such a deal would extend unemployment benefits and set the tone for a bigger deal with Republicans down the line.

In his own weekly address, Obama called this smaller deal "an achievable goal ... that can get done in 10 days."

But though there is no definitive way to say one way or the other whether it really is an achievable goal, one thing is for certain: Republican leadership does not agree with the president on this question.

Of reaching an agreement on the fiscal cliff by the deadline, Boehner said, "How we get there, God only knows."
