Gaza's civil defence agency said that Israeli strikes across the Palestinian territory on Sunday killed at least 44 people and wounded dozens more."The death toll as a result of Israeli air strikes since dawn today is at least 44, including 21 in Khan Younis," the Gaza Strip's main southern city, agency spokesman Mahmud Bassal said.In its daily report, Palestine's Ministry of Health said the death toll from the Israeli occupation's aggression on the Gaza Strip has risen to 50,695 martyrs in addition to 115,338 wounded since October 7, 2023.It added that the death toll and injuries since the renewed Israeli aggression on March 18 has reached 1,335 martyrs and 3,297 wounded.It noted that a number of victims are under the rubble and on the streets, unable to be reached by ambulances and civil defense crews.The Israeli occupation resumed its aggression on the Gaza Strip at dawn on March 18, after a two-month pause under a ceasefire agreement that came into effect on January 19.Reuters adds from Jerusalem: The Israeli military has provided new details that changed its initial account of the killing of 15 emergency workers near the southern Gaza city of Rafah last month but said investigators were still examining the evidence.The 15 paramedics and emergency responders were shot dead on March 23 and buried in a shallow grave where their bodies were found a week later by officials from the United Nations and the Palestinian Red Crescent. Another man is still missing.The military initially said soldiers had opened fire on vehicles that approached their position "suspiciously" in the dark without lights or markings. It said they killed nine militants from Hamas and Islamic Jihad who were travelling in Palestinian Red Crescent vehicles.But video recovered from the mobile phone of one of the dead men and published by the Palestinian Red Crescent showed emergency workers in their uniforms and clearly marked ambulances and fire trucks, with their lights on, being fired on by soldiers.The only known survivor of the incident, Palestinian Red Crescent paramedic Munther Abed, also said he had seen soldiers opening fire on clearly marked emergency response vehicles.An Israeli military official said late on Saturday the investigators were examining the video and conclusions were expected to be presented to army commanders on Sunday.He said the initial report received from the field did not describe lights but that investigators were looking at "operational information" and were trying to understand if this was due to an error by the person making the initial report."What we understand currently is the person who gives the initial account is mistaken. We're trying to understand why."Israeli media briefed by the military reported that troops had identified at least six of the 15 dead as members of militant groups. However, the official declined to provide any evidence or detail of how the identifications were made, saying he did not want to share classified information.The UN and Palestinian Red Crescent have demanded an independent inquiry into the killing of the paramedics.Red Crescent and UN officials have said 17 paramedics and emergency workers from the Red Crescent, the Civil Emergency service and the UN had been dispatched to respond to reports of injuries from Israeli air strikes.Apart from Abed, who was detained for several hours before being released, another worker is still missing.The UN said last week that available information indicated one team was killed by Israeli forces and other emergency and aid crews were killed one after another over several hours as they searched for their missing colleagues."We need justice for the victims and we need to ensure that all of those who are responsible are held to account," said Palestinian Red Crescent spokesperson Nebal Farsakh. "Without this, the crimes will continue to happen."
