Along with the letters of accession to the ICC, Palestine has reportedly filed a request to the Hague to investigate Israeli war crimes during the 50-day war in Gaza last summer. Palestinian president Mahmoud Abbas signed the request to probe IDF's use of force starting June 13, 2014, along with the letters of accession to the International Criminal court on Wednesday night, an unnamed NGO worker told Haaretz. On Friday the batch of newly signed documents and the petition are expected to be received by the UN Secretary-General.
