A stampede at a food distribution site run byan Israeli-backed American organizationin the Gaza Strip killed 20 Palestinians on Wednesday, the group said, in the first acknowledgment of deadly violence at its operations. The Gaza Humanitarian Fund, an American organization backed by Israel to feed the Gaza Strip's population, said 19 people were trampled in a stampede and one person was fatally stabbed at a hub in the southern city of Khan Younis. The organization accused the Hamas militant group of fomenting panic and spreading misinformation that led to the violence, though it provided no evidence to support the claim. The deaths came as Israeli strikes killed 41 others, including 11 children, in Gaza City and Khan Younis, according to hospital officials. The Israeli military said it has struck more than 120 targets in the past 24 hours across the Gaza Strip, including Hamas military infrastructure of tunnels and weapons storage facilities. Israel blames Hamas for the civilian deaths because the group often operates in residential areas. Here's the latest: Israel strikes near defense ministry in Damascus The Israeli army said Wednesday that it struck near the entrance to the Syrian Ministry of Defense in Damascus, as clashes continued in the southern Syrian city of Sweida after a ceasefire between government forces and Druze armed groups collapsed. Israel has launched a series of airstrikes on convoys of government forces in southern Syria since the clashes erupted and has beefed up forces on the border. It has said it is acting to protect the Druze religious minority. The Druze religious sect began as a 10th-century offshoot of Ismailism, a branch of Shiite Islam. More than half the roughly 1 million Druze worldwide live in Syria. Most of the other Druze live in Lebanon and Israel, including in the Golan Heights, which Israel captured from Syria in the 1967 Mideast War and annexed in 1981. Stun grenades and pepper spray caused chaos at food distribution site Gaza's Health Ministry and witnesses said GHF workers used tear gas against the crowd outside one of its food distribution hubs, causing a panic. The ministry said that it was the first time people have been killed by a stampedeat the aid sites. "They used stun grenades and pepper spray against us. They had aid inside, but they intentionally did not distribute it to let people crowd outside,″ said Abdullah Aleyat, who was at the GHF site on Wednesday morning. Omar Al-Najjar, a resident of the nearby city of Rafah, said people were gasping for air, possibly from tear gas. The injuries were "not from gunfire, but from people clustering and pushing against each other," Al-Najjar said as he carried an injured stranger to a hospital. The sites are inside Israeli military zones protected by private American contractors. Israel troops surround the sites, but the army says they are not in the immediate vicinity. The United Nations human rights office and Gaza's Health Ministry said Tuesday that 875 Palestinians in the enclave have been killed while seeking food since May, with 674 of those in the vicinity of aid distribution sites run by GHF.
