At least 18 civilians were killed and six wounded Sunday in a suicide car bomb attack near a military base in Afghanistan’s eastern province of Khost, where Afghan and foreign soldiers are stationed.

At least 18 civilians were killed and six wounded Sunday in a suicide car bomb attack near a military base in Afghanistan's eastern province of Khost, where Afghan and foreign soldiers are stationed.

The bomber detonated the explosives at a military roadblock near the entrance to Camp Chapman as people were rushing to get home for iftar, the meal breaking the Ramadan fast, said Faizullah Ghairat, the Khost city police chief.

There was no immediate claim of responsibility, but the Taliban -- which last week held its first face-to-face peace talks with the Afghan government -- has often targeted Afghan troops and people.

"We counted 18 dead and six wounded," said a doctor at a hospital in Khost city Sunday.

Ghairat put the toll at 25 dead and 16 wounded, adding that they were all civilians.

Foreign troops including US soldiers are stationed at Camp Chapman alongside Afghan soldiers.

A statement from the NATO mission in Afghanistan said it was "aware" of the blast, but did not elaborate.

In 2009, Camp Chapman, four kilometers, (2.4 miles) from the city of Khost was the target of a spectacular suicide attack claimed by Al-Qaeda. Seven CIA American officials were killed in the deadliest assault on the US agency since 1983, when eight officers died in an attack on a military base in Beirut during the Zionist invasion into Lebanon.

Earlier Sunday, officials said at least two civilians had been killed in a roadside bomb blast, blaming the attack on the Taliban.

Four other Afghans and two police were wounded when a police vehicle hit the roadside bomb in Kunduz city, provincial police spokesman Sayyed Sarwar Husseini told AFP.

Roadside bombs have been the Taliban's weapon of choice in their war against Afghan security forces. The bombs also increasingly kill and wound civilians.
