UNITED NATIONS — U.N. Secretary-General Ban Ki-moon said late Tuesday that the state of Palestine will join the International Criminal Court on April 1, a high-stakes move that will enable the Palestinians to pursue war-crimes charges against Israel.

The Palestinians submitted the documents ratifying the Rome Statute that established the court last Friday, the last formal step to accepting the jurisdiction of the world’s permanent war crimes tribunal. The U.N. said the secretary-general would review the paperwork.

In a statement posted on the U.N.’s treaty website, the secretary-general announced his acceptance of the documents.

Palestinian President Mahmoud Abbas signed documents to join the ICC a day after the U.N. Security Council rejected a resolution on Dec. 30 that would have set a three-year deadline for the establishment of a Palestinian state on lands occupied by Israel.

Joining the ICC is part of a broader Palestinian strategy to pressure Israel into withdrawing from the territories and agreeing to Palestinian statehood.
