Complicity. "Mortars fired from UN Gaza school," from the [1] BBC (thanks to Matthew):

The UN secretary general has ordered an investigation into an incident in which Palestinian militants fired mortars at Israel from a UN-run school in Gaza.

Ban Ki-moon condemned the abuse of UN facilities and described it a "serious violation of the UN's privileges and immunities", a spokeswoman said.

Israeli military aircraft filmed the mortars being fired from the school's playground in Beit Hanoun last week.

The UN has already complained about the incident to the authorities in Gaza.

The coastal territory has been controlled by the Islamist movement, Hamas, since it seized control from the rival Fatah group of Palestinian Authority President Mahmoud Abbas in June.
