Medics in Gaza have said about 68 people were killed and dozens injured overnight and into Friday morning in Israeli strikes on the city of Deir Al-Balah, the Nuseirat camp and the town of Al-Zawayda, all in Gaza’s central area, as well as in its south.

According to Reuters, 14 people were killed by an Israeli strike at the gate of a school sheltering displaced Palestinians in Nuseirat, according to medics at the camp’s Al-Awda Hospital. Another 10 were killed in a car in Khan Younis, medics said.

Hours later, residents said Israeli tanks advanced on the northern and eastern sides of Nuseirat, and medics said an Israeli airstrike killed four people, including three children.

The Israeli military said its troops killed what it called armed terrorists in central Gaza and the northern Jabalia area. It had no immediate comment on the reported school strike, although it habitually denies deliberately attacking civilians.

Israel also pummelled Beirut’s southern suburbs on Friday morning with at least 10 strikes, Reuters journalists said. It was the first bombardment of the area — once a densely packed district and Hezbollah stronghold — in nearly a week.
