The prosecutor of the International Criminal Court has said he had received a joint request from five countries to investigate the situation in the Palestinian territories, Reuters reports.

Prosecutor Karim Kahn said the referral had come from South Africa, Bangladesh, Bolivia, Comoros, and Djibouti. South Africa said the request was made “to ensure that the ICC pays urgent attention to the grave situation in Palestine.”

The ICC already has an ongoing investigation into “the situation in the State of Palestine” for alleged war crimes committed since June 13, 2014.
