CAIRO — Egyptian mediators held talks Saturday to firm up an Israel-Hamas cease-fire, as Palestinians in the Hamas-ruled Gaza Strip began to assess the damage from 11 days of intense Israeli bombardment. Saturday marked the first full day of a truce that ended the fourth Israel-Hamas conflict in just over a decade. Separately, a 130-truck convoy with humanitarian aid and medical supplies reached the Gaza border from Egypt on Saturday, according to a senior Egyptian official at the border crossing. He spoke on condition of anonymity because he was not authorized to speak to reporters. In the fighting, Israel unleashed hundreds of airstrikes that they said were against militant targets in Gaza, while Hamas and other militants fired more than 4,000 rockets toward Israel. More than 250 people were killed, the vast majority of them Palestinians, including scores of children. Gaza City"s busiest commercial area, Omar Al-Mukhtar Street, was covered in debris, smashed cars and twisted metal after a 13-floor building in its center was flattened in an Israeli airstrike. Merchandise was covered in soot and strewn inside smashed stores and on the pavement. Municipal workers swept broken glass and twisted metal from streets and sidewalks. "We really didn"t expect this amount of damage," said Ashour Subeih, who sells baby clothes. "We thought the strike was a bit further from us. But as you can see not an area of the shop is intact." Having been in business for one year, Subeih estimated his losses were double what he has made so far. The United Nations says approximately 800,000 people in Gaza do not have regular access to clean piped water, as nearly 50% of the water network was damaged in the recent fighting. Quoting Gaza"s public works and housing ministry, the UN"s office for the Coordination of Humanitarian Affairs said nearly 17,000 residential and commercial units have been damaged or destroyed in the 11-day campaign. These include 769 housing and commercial units that have been rendered uninhabitable, at least 1,042 units in some 258 buildings, which have been destroyed and another 14,538 units that have suffered minor damage. Both Israel and Hamas have claimed victory. There was a widespread expectation that the cease-fire would stick for now, but that another round of fighting at some point seems inevitable. Underlying issues remain unresolved, including an Israeli-Egyptian border blockade, now in its 14th year that is choking Gaza"s more than two million residents and a refusal by the militant Hamas to disarm. The barrage came after days of clashes between Palestinian protesters and Israeli police at the Al-Aqsa Mosque compound. Heavy-handed police tactics at the compound and the threatened eviction of dozens of Palestinian families by Jewish settlers inflamed tensions. On May 10, Hamas militants in Gaza fired long-range rockets toward Jerusalem, and Israel started airstrikes into the overcrowded Gaza Strip. The war has further sidelined Hamas" main political rival, the internationally backed Palestinian Authority, which oversees autonomous enclaves in the Israeli-occupied West Bank. Hamas" popularity seemed to be growing as it positioned itself as a defender of Palestinian claims to Jerusalem. On Friday, hours after the cease-fire took effect, thousands of Palestinians in the Al-Aqsa compound chanted against Palestinian President Mahmoud Abbas and his self-rule government. It was an unprecedented display of anger against Abbas. The conflict also brought to the surface deep frustration among Palestinians, whether in the occupied West Bank, Gaza or within Israel, over the status quo, with the Israeli-Palestinian peace process all but abandoned for years. Despite his weakened status, Abbas will be the point of contact for any renewed US diplomacy, since Israel and the West, including the United States, consider Hamas a terrorist organization. US Secretary of State Antony Blinken is to meet with Abbas and Israeli leaders when he visits in the coming week. Abbas is expected to raise demands that any Gaza reconstruction plans go through the Palestinian Authority to avoid strengthening Hamas. Abbas met Saturday with Egyptian mediators, discussing the rebuilding of Gaza and internal Palestinian relations, according to the official Palestinian news agency Wafa. An Egyptian diplomat said Saturday that two teams of mediators are in Israel and the Palestinian territories to continue talks on firming up a cease-fire deal and security long-term calm. The diplomat said discussions include implementing agreed-on measures in Gaza and Jerusalem, including ways to prevent practices that led to the latest fighting. He did not elaborate. He was apparently referring to violence at the Al-Aqsa Mosque and the planned eviction of Palestinian families from the Sheikh Jarrah neighborhood in east Jerusalem. The diplomat spoke on condition of anonymity to discuss behind-the-scenes deliberations. — Euronews
