The Palestinians have submitted documents to the United Nations to join the International Criminal Court, a move that will soon enable them to seek war crimes charges against Israel.

The Palestinian ambassador to the United Nations, Riyad Mansour, delivered the documents — known as instruments of ratification — to Assistant Secretary-General for Legal Affairs Stephen Mathias on Friday.

The International Criminal Court has recognized the U.N. General Assembly's recognition of Palestine as an observer state. Handing over the documents is the last formal step for Palestine to become a member of the ICC, which would take at least 60 days.

Palestinian President Mahmoud signed the documents after the U.N. Security Council rejected a resolution setting a three-year deadline for the establishment of a Palestinian state on lands occupied by Israel.
