Motorcycle bomb kills 2 in crowded market in southern Afghanistan

Police say a motorcycle bomb has killed two civilians in Afghanistan's southern Helmand province.

Police chief Haji Tooryali said the remote-controlled bomb wounded another 10 people on Tuesday in a crowded market inside the town of Marjah.

Taliban spokesman Qari Yousef Ahamdi denied any responsibility for the attack.

Bombs in vehicles, along roadsides and carried by suicide bombers are the leading cause of civilian casualties in Afghanistan. The United Nations has blamed insurgents for the overwhelming majority of such attacks, and said they have increased sharply this year as the Taliban try to regain territory as foreign troops withdraw.
