Germany's top human rights official has urged Israel to cooperate with the International Criminal Court probe into possible war crimes in the Palestinian territories.

After the investigation was announced last week, Israel's government immediately said it would not work with The Hague-based court and called for its funding to be cut.

The government's human rights commissioner, Christoph Straesser, said in an interview published Tuesday that Israel's reaction was counter-productive.

Straesser told ipg-journal, published by a center-left think tank, that "Israel has launched its own investigations and should in my view cooperate with the International Criminal Court."

He added that "as far as the effort to suspend funding for the court goes, I can only warn against adopting this proposal."
