Prosecutors at the International Criminal Court are looking into the reported death of Hamas military leader Mohammed Deif and will withdraw their case against him if they can confirm it, legal filings made public showed, Reuters reports.

Deif, 58, was believed to be one of the masterminds of the Oct 7 assault on southern Israel which triggered the Gaza conflict, and since then had directed Hamas military operations against Israeli forces in the Palestinian enclave.

Israel said he was killed in an Israeli airstrike on Gaza’s southern city of Khan Younis on July 13. Hamas has neither neither confirmed nor denied that.

“The prosecution will withdraw its (arrest warrant) application against Deif if sufficient and reliable information confirms his death,” the legal document, filed under under seal on August 2 but only revealed on Tuesday, said.

Last Friday the ICC announced it had terminated proceedings against Hamas leader Ismail Haniyeh, who was assassinated in Iran on July 31.
