Taliban Announces 'Spring Offensive'

The Taliban announced that its "spring offensive" in Afghanistan will officially begin on Thursday, the Associated Press reported, but no details were released.

The annual campaign comes on the heels of President Obama's surprise visit to Afghanistan on Tuesday. After signing an agreement with Afghan President Hamid Karzai, the president said that the U.S. will turn over combat operations to the Afghans in 2014.

A bomb exploded shortly after Obama left Afghanistan, killing 7 people and sending 18 more to the hospital, in an attack for which the Taliban took credit.
