Officials in Afghanistan say a suicide car bombing Sunday in Helmand province has killed 11 people and wounded a dozen more.

A provincial spokesman says 10 police officers and a child were killed in the blast near police headquarters in the southern city of Lashkar Gah. He said three civilians were among the wounded.

The Taliban has claimed responsibility for the attack.

Security for Lashkar Gah was handed over this month from foreign to Afghan forces, part of the first stage of a plan to have all of Afghanistan under the oversight of Afghan security forces by the end of 2014.

In eastern Afghanistan, NATO says one of its service members was killed Sunday in a bomb blast.
