WASHINGTON (AP) — Secretary of State Antony Blinken is heading again to the Middle East, making his 11th trip to the region since the Gaza war erupted last year and as Israel steps up attacks against Hezbollah in Lebanon.

The State Department said Blinken will depart on Monday for a weeklong trip to Israel and a number of Arab countries, on a visit that also comes as Israel weighs retaliation against Iran for ballistic missile attacks earlier this month.

The trip had been expected after President Joe Biden said last week he would dispatch Blinken to the region following Israel's killing of Hamas military chief Yahya Sinwar, a move that some believe could open a window for new talks on a cease-fire proposal that has been languishing for months.

"Throughout the region, Secretary Blinken will discuss the importance of bringing the war in Gaza to an end, securing the release of all hostages, and alleviating the suffering of the Palestinian people. He will continue discussions on post-conflict period planning and emphasize the need to chart a new path forward that enables Palestinians to rebuild their lives and realize their aspirations free from Hamas' tyranny," State Department spokesman Matthew Miller said in a statement.

He said Blinken would also underscore the need for a dramatic increase in the amount of humanitarian aid reaching Gaza, something that Blinken and Defense Secretary Lloyd Austin made clear in a letter to Israeli officials last week. That letter reminded Israel that the Biden administration could be forced by U.S. law to curtail some forms of military aid should the delivery of humanitarian assistance continue to be hindered.

In addition to the conflict in Gaza, Blinken will also raise the importance the administration places on reaching a diplomatic resolution to the escalating conflict between Israel and Hezbollah in southern Lebanon and elsewhere.

"He will reaffirm the U.S. commitment to work with partners across the region to de-escalate tensions and provide lasting stability," Miller said in the statement.

Since the Hamas attacks in Israel on Oct. 7, 2023 and the Israeli response, Blinken has traveled to the Middle East 10 times seeking an end to the crisis. His previous trips have yielded little in the way of ending hostilities but he has managed to increase aid deliveries to Gaza in the past.
