Condemnations poured in from the United Nations, the EU and media rights groups Monday after an Israeli strike killed an Al Jazeera news team in Gaza, as Palestinians mourned the journalists and Israel accused one of them of being a Hamas militant.

Five staff members of the Doha-based Al Jazeera Network were targeted in the early hours of Monday in Gaza City. The network has condemned the targeting of its journalists, calling the strike “deliberate assassinations.

A prominent Al Jazeera journalist, who had previously been threatened by Israel, was killed along with four colleagues in an Israeli airstrike in an attack condemned by journalists and rights groups.
