Suicide Attack on Afgan US Firm

A suicide bomb attack on a US security firm convoy on the outskirts of the south Afghan city of Kandahar has killed 15 people and injured 20. The bombing, the second suicide attack in Kandahar in as many days, took place on the main road heading west to the troubled province of Helmand. At least six of the dead were civilians including women and children and at least three were security guards. More than 3,700 people have been killed in Afghan violence this year.
