"I note with great concern the escalation of violence in the West Bank, including East Jerusalem, as well as in and around Gaza, and the possible commission of crimes under the Rome Statute," the prosecutor tweeted.

"My office will continue to monitor developments on the ground and will factor any matter that falls within its jurisdiction."

Bensouda said she echoed calls from the international community to de-escalate the situation, urging "calm" and "restraint."
