Carnage as Taliban bomber hits police convoy

More than 30 people were killed Thursday when at least one suicide bomber attacked a convoy of buses transporting police recruits in Afghanistan to the capital city, an Afghan official tells CBS News.

The 200 police cadets were traveling to Kabul from neighboring Wardak province, where they were in training, for leave for the Muslim holiday of Eid, in five buses when the convoy was attacked.

Paghman District Chief Haji Musa Khan told CBS News there was an initial explosion which appeared to be smaller, but prompted the buses to stop as the cadets tended to the wounded. There was then a larger second blast.
