U.S. Secretary of State Antony Blinken is heading to the Middle East this week amid intense diplomatic efforts to facilitate the delivery of humanitarian aid into the war-ravaged Gaza Strip and increasing international pressure on Israel to reduce civilian casualties among Palestinians, VOA reported. Blinken's visit would come as Israel's war with Hamas militants approaches its three-month mark. Amos Hochstein, a senior adviser to U.S. President Joe Biden, will also travel to Israel to work toward calming tensions between Israel and Hezbollah. The State Department said the United States remains “incredibly concerned” about the risk of the conflict spreading into other fronts, after the killing Tuesday of senior Hamas official Saleh al-Arouri in Beirut. The U.S. has sent a “very direct message to Hezbollah” and other entities in the region that “now is not the time to think of escalating further,” according to the State Department. “You've seen us take deterrence steps to deliver that message. You've seen us take diplomatic steps to deliver it. We'll continue to deliver it,” State Department spokesperson Matthew Miller told reporters during a briefing on Wednesday. The United Nations Interim Force in Lebanon (UNIFIL) has also voiced deep concern at any potential for escalation, while urging all parties to exercise restraint.
