A court in southern Egypt has convicted 529 supporters of ousted Islamist President Mohammed Morsi, sentencing them to death on charges of murdering a policeman and attacking police.

The court in Minya issued its ruling on Monday after only two sessions in which the defendants' lawyers complained they had no chance to present their case.

Those convicted are part of a group of 545 defendants on trial for the killing of a police officer, attempted killing of two others, attacking a police station and other acts of violence.

More than 150 suspects stood trial, the others were tried in absentia. Sixteen were acquitted.

The defendants were arrested after violent demonstrations that were a backlash for the police crackdown in August on pro-Morsi sit-ins in Cairo that killed hundreds of people.
