Horrifying images have emerged from Israel’s latest attack on a school-turned-shelter in Gaza City, with a video purporting to show a young girl scrambling for safety after the classroom she was sleeping in was engulfed by flames.

In an 11-second clip shared on the messaging site Telegram, a young girl can be seen trying to make her way out of a burning classroom following a deadly Israeli strike on the Fahmi Al-Jargawi girls’ school.

Health officials told reporters they had recovered the severely burned bodies of 31 people, including children, after the late-night strike.
