A homicide bomber struck a road construction crew Saturday in southwestern Afghanistan, killing two people including an Indian engineer, a provincial governor said.

Ghulam Dastagir said the engineer and his Afghan driver were killed when the bomber hit members of an Indian construction crew in Khash Rod district of Nimroz province. Initially, Dastagir said three Indian engineers were killed, but he later revised that figure.

Eight other people, including five Indian workers and two civilians, were wounded in the blast, he said.

The bomber approached the construction site on foot, the governor said.

Homicide attacks in Afghanistan spiked in 2007, with the Taliban launching more than 140 suicide missions, the highest number since the radical Islamist group was ousted from power by a U.S.-led invasion in 2001.

The U.N. says more than 8,000 people were killed in insurgency-related violence in 2007.
