Police in Papua New Guinea have opened fire on students protesting against Prime Minister Peter O’Neill.
Several students were injured and there are unconfirmed reports of at least one death.
The students were marching from their campus in the capital, Port Moresby, towards parliament, where Mr O’Neill faces a motion of no confidence.
They are demanding that he stand down over corruption allegations, which he denies.
Footage obtained by the BBC appeared to show a large crowd of students at the campus running away as shots and tear gas were fired.
Medical officials in Port Moresby told Reuters that at least 10 students had been admitted “in a difficult situation”.
Images circulating on social media also showed injured students being carried away.
Gary Juffa, an MP and vocal critic of the prime minister, said on Twitter he had been told the shooting began with an argument between one student and a police superintendent.
Reports suggest the students had refused to hand over their protest leader to police.
Australia’s ABC News said parliament had been told four people were dead.
The students have been protesting and boycotting classes for the past five weeks.
Mr O’Neill has consistently denied wrongdoing and has refused to stand down.
