Hamas says that it is on the verge of starting its own investigation into whether it committed war crimes during Israel's war on Gaza.<br /><br />The probe is one of the main requirements of the recent UN-backed Goldstone Report into the conflict, which took place during December and January. Most of the report's criticism was reserved for Israel. <br /><br />In a rare interview, Ismail Haniya, the deposed Palestinian prime minister, also told Al Jazeera's Zeina Awad that he is still hopeful of exchanging Gilad Shalit, a captured Israeli soldier, for Palestinian prisoners held in Israeli jails.
