A university student has been killed and another seriously injured by stray bullets as gunmen shot dead two men in a parked car on a busy street near the centre of the South African city of Johannesburg, police say.

The students were hit when their bus was passing the scene of the shooting.

No arrests have so far been made.

Gun crime claims dozens of lives every day in South Africa but witnesses to these killings in broad daylight said they were shocked by what happened.

“Both the men in the vehicle and one student were declared dead while the other student was taken to the nearest hospital for medical treatment,” police spokesperson Col Dimakatso Nevhuhulwi told the BBC when describing what happened on Thursday afternoon.

A police statement said the students had been caught in “crossfire”.
