At least two Indian road workers have been killed in a double suicide bombing in southwestern Afghanistan, according to officials.

Five other people were wounded in the attack in Khash Rod district of Nimruz province on Saturday.

Afghan authorities said they captured a third potential suicide bomber.

"There was a suicide attack carried out by two suicide bombers against Indian road workers who were working on a bridge" Ghulam Dastgir Azad, the provincial governor, was reported by the AFP news agency as saying.

"Two Indian engineers were killed. Several other people including three Indians were injured."

The wounded included three other Indians, their Afghan driver and a policemen, Azad said.

The blast comes after a suicide-car bombing in the southern province of Kandahar which killed eight civilians on Thursday.

Taliban claim

Yousuf Ahmadi, a purported spokesman for the Taliban, claimed responsibility but gave a different version of the attack.

He said at first two mines planted by fighters were detonated, after which a bomber blew himself up.

"It was carried out by our mujahidin," Ahmadi said.

"First they detonated two mines that we had buried in the area. After police and the Indians gathered there one of our devoted members carried out a suicide bombing," Ahmadi said.
