Attack on convoy carrying goods to Afghan capital Kabul kills 3 drivers

Attack on convoy carrying goods to Afghan capital Kabul kills 3 drivers: 
"It was unclear if the trucks were carrying supplies for the US-led military coalition or if they had commercial goods, Zwak said, but he added that no international troops or military vehicles were in the convoy. He said the drivers were Afghan.
Attacks on supply trucks coming to Kabul are relatively common, as Taliban and other militants seek to disrupt both flow of the military goods and sow fear among the population.
The latest attack comes in a period of intense violence, with the Taliban targeting police and civilian officials and attacking government positions around the country as Afghan police and army prepare to officially take over full responsibility for security from international troops."
