Israel and Qatar, which backs Al Jazeera and has hosted Hamas leaders, have long had a relationship marked by both public hostility and quiet collaboration.

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.

Israel’s military has targeted and killed an Al Jazeera correspondent and others with an airstrike as they sheltered outside a Gaza City hospital.
