The ICC already has an ongoing investigation into "the situation in the State of Palestine" for alleged war crimes committed since June 13, 2014.
Last month ,Kahn said that his office had jurisdiction both over Hamas' attack on Israel on Oct. 7 and any crimes committed as part of Israel's response including bombings in the Gaza Strip.
In a statement, the prosecutor's office said it had so far "collected a significant volume of information and evidence" on crimes in the Palestinian territories and also committed by Palestinians.
The ICC can investigate nationals of non-member states in certain circumstances, including when crimes are alleged to have been committed in the territories of member states.
The Palestinian territories have been listed among the ICC's members since 2015.
