The UN’s humanitarian aid chief Tom Fletcher has described the killing of a UN staff member and the wounding of five others in an attack in Gaza as “infuriating”, Al Jazeera reports.

Fletcher said the strikes targeted a “clearly designated” UN compound in Gaza, and the UN demands “answers” while “we grieve with the family of our colleague”.

“International law is clear. Civilians — including UN staff and humanitarian workers — must not be targeted. The international community must join us in insisting on a genuine investigation and accountability,” Fletcher said in a statement, without attributing blame for the killing.

Earlier, Hamas said the Israeli military is guilty of a “heinous crime” for targeting UN staff for attack in order to “terrorise” aid workers still operating in Gaza.
