FILE - In this Friday, April 26, 2013 file photo, Afghan police and army soldiers inspect a burned bus after it collided with the wreckage of a truck that was attacked by Taliban insurgents in Maiwand district, on the highway between Kandahar and Helmand, Afghanistan. The Taliban have announced they will launch their spring offensive on Sunday, April 28, 2013, signaling plans to step up attacks as the weather warms across Afghanistan, making both travel and fighting easier.
