Ferguson police shot during protest
Two police officers have been shot in Ferguson, a Missouri town hit by riots over the killing of an unarmed black teenager last year, the BBC reported.
One officer was shot in the face and one in the shoulder, St Louis County police chief Jon Belmar said.
Both suffered "very serious gunshot injuries" but were conscious, he said.
They were shot during a demonstration after the resignation of Ferguson's police chief, which followed a report alleging racial bias in his department.
Protesters had gathered outside Ferguson police headquarters late on Wednesday, in what was initially a relatively low-key demonstration.
But shortly after midnight at least three shots were fired as the crowd of protesters was starting to break up, Mr Belmar said.
He said he was assuming that "these shots were directed exactly at my police officers", rather than the officers being hit by stray bullets.
One protester, Keith Rose, said he saw an officer "covered in blood", and that other officers were carrying and dragging him, leaving a trail of blood on the ground.
Police were keeping protesters in the area in order to take witness statements, he said.
Demonstrators were calling for further action to be taken over the federal report, and for more resignations in the police department, Mr Rose said.
