Israeli strike on UN school in Gaza kills at least 20, locals say

An Israeli airstrike on a UN school in central Gaza has killed at least 27 people, including women and children, and injured hundreds.

The school was housing displaced people. Israel claims the school was being used as a Hamas compound, but Hamas and local residents deny this.

The attack has been condemned as a "horrific massacre". The strike is part of an ongoing Israeli military operation in Gaza, which has seen intense bombardment and reports of widespread destruction.

Medical charity MSF has described the situation as "apocalyptic" and appealed for urgent assistance.
