Israel Says Hamas Stages Hit-and-Run Attacks From Tunnels1 min read

The Israeli Defence Forces (IDF) said soldiers were engaged in close quarters combat with Hamas fighters staging hit-and-run attacks from tunnels.

The UN said four of its schools being used as shelters had been damaged and warned water shortages were worsening.

The Hamas-run health ministry says over 9,000 Palestinians have been killed.

On Thursday the UN Relief and Works Agency (UNRWA) said four of its schools being used as shelters hade been damaged in less than 24 hours.

At least 20 people were reportedly killed at a school in the Jabalia refugee camp, UNRWA said, while a child was reportedly killed at a school-turned-shelter in the Beach refugee camp.

The BBC has verified two videos from the schools.

One extremely graphic video, filmed at an elementary school in the Jabalia refugee camp in northern Gaza, shows the aftermath, first outside the main gate of the school and then in the main courtyard.

At least 20 people, either dead or injured, can be seen on the ground, including men, women and children.

The second video, filmed at the main courtyard of a primary school in Beach refugee camp, also in northern Gaza but near the Mediterranean coast, shows a plume of smoke rising from behind the main building of the school.

Several people, including children, run for safety in the courtyard, while some residents of the camp watch from the windows above. A series of explosions can be heard in the background of the video. The last one, the loudest, causes the crowd in the courtyard to flee in panic.

Hamas authorities in Gaza blamed Israeli air strikes. The IDF has not yet commented.
