A former police officer accused of leading a massacre of 2,000 people in Rwanda’s genocide appeared in court again and may face more charges.

The court adjourned until 9 June after Fulgence Kayishema was charged with 14 crimes, including genocide and crimes against humanity. The state said it would review more files and add more charges later.

Kayishema, who used a fake name and claimed to be from Burundi, sought asylum in South Africa in 2000. He was arrested last month at a farm near Cape Town.

He allegedly participated in one of the worst atrocities of the genocide, when thousands of people who hid in a church were killed.

A survivors’ group called for his repatriation to Rwanda for trial. His lawyer said he was calm and denied any involvement in the killings.

Kayishema was indicted by a UN tribunal for his role in the genocide, which claimed the lives of 800,000 Tutsis and moderate Hutus in 1994.
