UN human rights chief Volker Turk says the UN has recorded 136 Israeli attacks on 27 health facilities in Gaza, which have caused “significant death and destruction”, Al Jazeera reports.

While Israel often states that Palestinian armed groups use such facilities for military purposes, Turk said Israel has not backed up those claims with evidence.

“Israel has not provided sufficient information to substantiate many of these claims, which are often vague and broad. In some cases they appear to be contradicted by publicly available information,” Turk said in remarks to the United Nations Security Council.

Turk called for an independent investigation to probe Israel’s attacks on hospitals and the allegations that Hamas is using those facilities for military purposes.
