US President Joe Biden was received by Israeli Prime Minister Benjamin Netanyahu at the Ben Gurion Airport on Wednesday as he arrived on a solidarity visit on the twelfth day of the conflict between Israel and Hamas.
He said he was "sad and outraged" by an explosion at a hospital in the Gaza Strip that left at least 500 dead on Tuesday and blamed the "other side" for the explosion.
Earlier, US National Security Council spokesman John Kirby said the president will push for a humanitarian corridor into Gaza and will ask some "tough questions" about "the situation on the ground".
He will also meet with the families of hostages held in Gaza.
It comes as Biden's meeting with leaders of Jordan, Egypt and Palestine in Amman on Wednesday was cancelled after a strike on Gaza's Al Ahli Arab Hospital killed more than 500 people.
