In Afghanistan seven U.S. soldiers died Thursday in an explosion at an ammunition dump southwest of Kabul. The cause of the explosion is not known. It was one of the deadliest days for U.S. forces since they invaded Afghanistan two years ago. Meanwhile the Taliban has taken credit for carrying out separate suicide bombing attacks in Kabul earlier this week that killed a British soldier and a Canadian soldier. And a U.S. military spokesperson said Thursday that the military is “sure” it will catch Osama Bin Laden this year.
