Israel also faced backlash from aid groups after its parliament passed legislation that could severely restrict the ability of the U.N. agency for Palestinian refugees to operate in the Palestinian territories.

Two Israeli airstrikes in the northern Gaza Strip on Tuesday killed at least 88 people, including dozens of women and children, health officials said, and the director of a hospital said life-threatening injuries were going untreated because a weekend raid by Israeli forces led to the detention of dozens of medics.

At least 60 people have been killed and another 17 are missing in an Israeli strike early Tuesday on a five-story building where displaced Palestinians were sheltering in the northern Gaza Strip.
