Israel has blamed Islamic Jihad Palestinian militants for they say was an errant bomb. Palestinian officials say Israel was responsible.

During this extraordinarily fraught visit, Biden will first assure Netanyahu of his support in the wake of the Hamas attacks and kidnappings last week, but he has pledged to raise humanitarian concerns with the prime minister, too, as Israel continues to pound the Gaza strip with missiles and still appears poised for a ground invasion. A humanitarian corridor to get basic supplies like water, food, and fuel to Palestinians in Gaza has yet to be opened.
