Chief Palestinian observer, Riyad Mansour, has confirmed that the documents had been passed on in statements to reporters at the UN.

"We are honored that we are to be the 123rd state party to join the ICC, which will become effective about 60 days from now," Mansour said at the UN as quoted by Al Jazeera.

"It is a very significant step which we will be taking. It is a legal option, it is a peaceful option, it is a civilized option and it is an option that anyone who upholds the law should not be afraid of."

Palestinian President Mahmoud Abbas signed the Rome Statute, the founding treaty to join the International Criminal Court, on Tuesday, a day after the UNSC failed to adopt the Arab coalition’s bid for the creation of a Palestinian state.

Palestine rep just finished speaking at UN. Specifically discussed ICC investigating Israel for both settlements and other war crimes.

On Thursday, Israeli Prime Minister Benjamin Netanyahu spoke out against the move saying that: “It is the Palestinian Authority – which is in a unity government with Hamas, an avowed terrorist organization that, like ISIS, perpetrates war crimes – that needs to be concerned about the International Criminal Court in the Hague.”

He added they would rebuff the attempt, according to a statement published on the PM's website.
