U.S. Secretary of State Antony Blinken was in Ankara, Turkey, on Monday, where he held a meeting with Turkish Foreign Minister Hakan Fidan.
Blinken has been carrying out a tour of the Middle East that included stops in Jordan and Iraq over the weekend. Turkey has been critical of Israel and called for a cease-fire. Ankara also supports a two-state solution.
The Rafah border crossing between Gaza and Egypt reopened to foreign nationals and badly injured Palestinians, the Gazan border authority said Monday.
Meanwhile, the Israel Defense Forces took control of a Hamas compound and struck over 450 aerial targets in an overnight operation, the military said in a Telegram update.
It said that the targeted compound included observation posts, training areas and underground tunnels, and that Hamas operatives were also killed during the offensive.
Elsewhere, leaders of United Nations agencies and humanitarian organizations have issued a joint statement calling for an immediate humanitarian cease-fire.
They called Palestinian militant group Hamas' terror attack on Oct. 7 "horrific," but said that the "horrific killings of even more civilians in Gaza is an outrage, as is cutting off 2.2 million Palestinians from food, water, medicine, electricity and fuel."
More than 10,000 Palestinians have been killed by Israeli attacks on Gaza since Oct. 7, according to the Hamas-run Palestinian Health Ministry.
The total number of deaths recorded over the 31 days of fighting is 10,022, including 4,102 children, the ministry said.
