Israeli air strikes hit UN-run school in Jabalia camp

Israeli air strikes have hit a United Nations-run school in Jabalia refugee camp in northern Gaza, according to media reports. 

Graphic footage aired by Al-Jazeera on Saturday showed scores of lifeless bodies following the attack on al-Fakhoora school, which is run by the UN Relief and Works Agency for Palestine Refugees (Unrwa).

The scale of casualties is not yet known.

The school had already been bombed days ago, and was previously targeted by Israeli forces during escalations of violence in 2009 and 2014.
