Israeli fighter jets carried out raids on the Gaza Strip on Monday, a day after the prosecutor of the International Criminal Court said the Palestinian territories were subject to a preliminary examination by her office and she was monitoring events there closely. The Israeli army said Monday that it targeted a Hamas "military target" in northern Gaza. Palestinian security sources in Gaza said the Israeli strikes hit a base in Jabalia belonging to Ezzedine al-Qassam Brigades, Hamas armed wing, and farmland near Beit Lahia, causing damages but no injuries. The Israeli strike came a day after suspects crossed the northern Gaza border fence, leaving "explosive devices" that were found by the army. The border fence between the Palestinian enclave and Israel has become the backdrop of mass Gaza demonstrations that lead to deadly clashes. On Monday, the Gaza health ministry said Marwan Qudeih, 45, who was wounded by Israeli fire east of Khan Yunis on March 30, died of his wounds. His death brings the number of Palestinians killed by Israeli forces since then to 31. Rights groups have harshly criticised Israeli soldiers actions, and Palestinians say protesters are being shot while posing no threat to troops. On Sunday, ICC chief prosecutor Fatou Bensouda said she was opening a preliminary probe to determine whether there was enough evidence to launch a full-blown investigation into any alleged crimes. "Any person who incites or engages in acts of violence including by ordering, requesting, encouraging or contributing in any other manner to the commission of crimes within ICCs jurisdiction is liable to prosecution before the Court," Bensouda said.
