British prosecutors have charged a 65-year-old doctor living in London over alleged involvement in the 1994 genocide against Tutsi people in Rwanda.

The Crown Prosecution Service says Dr. Vincent Brown, formerly known as Vincent Bajinya, faces one charge relating to conduct ancillary to genocide and six charges relating to conduct ancillary to murder as a crime against humanity. Prosecutors allege that he directed and encouraged acts carried out by others. He denies the allegations.

The Metropolitan Police’s war-crimes investigators began examining the case in 2019, following a request from the Rwandan government. Brown is originally from Kigali and later moved to the United Kingdom, where he obtained British citizenship under his current name.

He is due to appear before Westminster Magistrates’ Court, while British authorities say investigations into other alleged Rwandan genocide suspects living in the UK are continuing.

The case is significant because UK law permits prosecution of certain international crimes, including genocide and crimes against humanity, even when the alleged offences occurred outside Britain.
