Eight Afghan police officers 'killed in US air strikes'
At least eight Afghan police officers have been killed in two US air strikes in southern Uruzgan province in what was apparently a friendly-fire incident, an official said.
Rahimullah Khan, a provincial operational commander, said the first air strike killed one policeman at a checkpoint outside the provincial capital of Tirin Kot, while the second, which struck the same area, killed seven others.
Mr Khan said the air strikes took place on Sunday afternoon around Tirin Kot. The Taliban have been advancing on the city in recent weeks.
A US military spokesman confirmed that US forces carried out an air strike, saying they sought to assist Afghan troops who were fired on by the Taliban.
Brigadier General Charles Cleveland said he did not "have any further information" on who the casualties may have been.
