KABUL, Afghanistan >> Authorities say a roadside bombing in southern Afghanistan has killed six police officers.

Uruzgan provincial government spokesman Abdullah Emat says the policemen were driving in a pickup truck through the province’s Charcheno district on Sunday when the vehicle struck the explosive. He did not provide further details.

Meanwhile, the Italian defense ministry says an Italian soldier was killed and two others were wounded in an explosion Monday in western Afghanistan.

Local police spokesman Raouf Ahmadi says the Italian soldier died when a grenade went off inside a watchtower at the base. He says the grenade apparently got dropped by accident and exploded. Ahmadi says there was no sign of an attack.
