Official: Suicide blasts hit U.S.-Afghan base; 12 killed

Two suicide bombers struck a joint U.S.-Afghan military base in central Afghanistan early Saturday morning, killing 12 people, authorities said.

The attack also wounded 57 others, said Shahidullah Shahid, a spokesman for the provincial governor.

A majority of the casualties included civilians, but four Afghan police officers were among those killed, he said.

One bomber attacked the base on foot, then another one detonated a truck, the spokesman said.

No international coalition service members died in the attack in Sayedabad district, according to Maj. Adam Wojack, a spokesman for the International Security Assistance Force.

The Taliban claimed responsibility for the attack.

A United Nations report this month stated that violence against civilians fell in the first half of the year.
