The Israeli military escalated its operations in the Gaza Strip on Tuesday, killing at least 82 Palestinians in less than 24 hours.

According to the Palestinian Ministry of Health, more than 640 have been killed over eleven days of Israeli attacks on Gaza. More than 2,850 have been killed.

As many as 42 were killed when Israeli tank shells hit the UN-operated Al-Fakhoura school in Jabalya Refugee Camp, where Palestinians took shelter after fleeing their homes.

Separately, Palestinian cameraman Bsil Faraj, who works for an Algerian television network, succumbed to wounds he sustained days ago. Faraj died in Egyptian hospital where he was taken for treatment.

Earlier on Tuesday, Israeli forces targeted another UN school in Ash-Shati refugee camp in the northern Gaza Strip killing three people from one family. They were identified as 17-year-old Abid As-Sultan, 24-year-old Mahmoud As-Sultan and 26-year-old Jamal As-Sultan.

In the Zaytoun neighborhood in Gaza City, 13 members of the Ad-Daya family were killed, five of whom were removed from the rubble of their house on Tuesday morning; 59-year-old Fayiz Ad-Daya, his daughter 24-year-old Sabrin Ad-Daya, his son 34-year-old Iyad Ad-Daya, Iyad's wife, 26-year-old Rawda Ad-Daya and the couple's daughter 4-year-old Kawkab Ad-Daya. The other eight victims were removed in the evening.
