Kohat: A suicide bomber tried to ram his vehicle into a Pakistani military camp on Friday but was blown up when soldiers opened fire at him.

A military official said the bomber tried to ram an army truck carrying troops in the paramilitary camp in the Darra Adam Kheil region, south of Peshawar.

"The vehicle could not enter the gate and exploded when security people fired on it," said Siraj Ahmed, the region's top administration official.

Two civilians were killed and 20 paramilitary soldiers were wounded in the incident.
