ICC wants to intensify investigations into war crimes

Meanwhile, International Criminal Court (ICC) chief prosecutor Karim Khan called on Israel and Hamas to abide by international law and said his office would step up investigations into possible war crimes.

“All actors must comply with international humanitarian law. If you don’t, don’t complain when my office has to act,” Khan said on Sunday as he concluded his four-day visit to Israel and the occupied West Bank.

Khan stressed his visit was “not investigative in nature” but said he was able to speak to victims on both sides of the conflict.

“Credible allegations of crimes committed during the current conflict should be subject to a timely, independent review and investigation,” he said.

Established in 2002, the ICC is the world’s only independent court that investigates the most serious crimes, including genocide, war crimes and crimes against humanity. It opened an investigation in 2021 against Israel as well as Hamas and other Palestinian armed groups for possible war crimes in the Palestinian territories.

Khan also called for humanitarian aid to be allowed into the Gaza Strip immediately, adding that Hamas must not misuse this aid.

“As far as humanitarian access is concerned, the law leaves no room for doubt,” he said. “Civilians must have access to basic food, water and urgently needed medical supplies without further delay, quickly and at scale.”

He said that before Blocking the delivery of aid to Gaza could also constitute a war crime within the ICC’s jurisdiction.

Israel, which is not a member of the International Criminal Court, has previously rejected the court’s jurisdiction and does not officially participate in it.
