Secretary of State Antony J. Blinken met with Prime Minister Benjamin Netanyahu of Israel on Monday in Jerusalem, as the United States sought to put pressure on Hamas and Israel to agree to a cease-fire. Mr. Blinken reiterated that the United States and other world leaders would stand behind the proposal outlined by President Biden.

Following the Israeli rescue of four hostages in Gaza on Saturday, Israel’s military said that three of them had been held in the home of a member of Hamas, Abdallah Aljamal. Mr. Aljamal’s death was confirmed on Sunday by Gaza’s Government Media Office, which said he had worked for a Hamas-affiliated news agency, Palestine Now.
