CAIRO, July 30. /Dina Pyanykh for ITAR-TASS/. At least 20 people were killed and more than 90 wounded on Wednesday as a result of an Israeli strike on the UN-run Abu Haseen School in Jabaliya, according to Palestinian news agency Ma’an.

Artillery keeps attacking Jabaliya and Beit Lahia since morning. According to eyewitnesses, dozens of shells were fired at the school. One of the school’s pavilions, where displaced families from the eastern part of Gaza were hiding, was severely damaged.

Last week, another similar school in Beit Hanoun also came under attack. According to Palestinian sources, at least four shells were fired at the building: 15 people died, including women, children and UN employees. The Israeli side insists that Hamas militants are using schools, mosques, hospitals and other social infrastructure facilities as weapon storages, voluntarily using civilians as a shield against aviation and artillery strikes, as well as shooting missiles on Israeli settlements from these places after that.

According the Palestinian medical sources, the overall number of casualties in the past 24 hours exceeded 70 people. In Khan Yunis, in the south of Gaza Strip, bodies of seven victims were taken out from the debris of a residential house: they were members of one family and there were four women among them. The same number of people, including three children, died under the wreckage of a residential house in eastern Gaza. According the local Health Ministry, since the beginning of the military operation July 8, 1,238 people fell victims to bombings and shooting attacks, while more than 7,000 were wounded.

Meanwhile, representatives of the Hamas military wing Izz ad-Din al-Qassam Brigades stated that during their raid in Khan Yunis, they blew up a house with Israeli servicemen. As a result, 15 soldiers were injured.
