KABUL, July 28: Six people including two UN election workers were killed on Wednesday in an explosion in a mosque where the United Nations was registering people for elections, as an ammunition depot was blown up after a missile attack.

The US military in Afghanistan said at least two people were wounded in the bomb blast in Ghazni province to the southwest of Kabul. A spokesman for the UN in Kabul said he knew of only two people killed, both Afghans.

Meanwhile, an ammunition depot blew up near the Afghan capital after it was hit by a rocket, a spokesman for foreign peacekeepers said on Wednesday. The rocket attack, the third in less than two weeks in or around Kabul, happened hours before a missile landed just outside the Chinese embassy and not far from the presidential palace.

No one was hurt in Tuesday night's strikes, said commander Chris Henderson from the 6,500-strong International Security Assistance Force led by NATO. Separately, two soldiers from the 20,000-strong US-led force hunting remnants of the Taliban and Al Qaeda were wounded on Tuesday when their convoy was attacked. -Agencies
