Senate Majority Leader Chuck Schumer on Sunday said he and other members of a bipartisan delegation of senators were forced to shelter in Tel Aviv after Hamas fired a barrage of rockets while the lawmakers prepared to meet with Israeli leaders.

Schumer, D-N.Y., posted a photo on X showing himself, Sen. Mitt Romney, R-Utah, and others standing in a close-quarters shelter.

"While in Tel Aviv today, our delegation was rushed to a shelter to wait out rockets sent by Hamas," the majority leader wrote. "It shows you what Israelis have to go through. We must provide Israel with the support required to defend itself."

Schumer, the first Jewish Senate majority leader and the highest-ranking Jewish elected official in the U.S., led a bipartisan group of senators, including Republican Sens. Romney and Bill Cassidy of Louisiana and Democratic Sens. Jacky Rosen of Nevada and Mark Kelly of Arizona.

"I'll lead the effort in the US Senate to provide Israel with the support required to defend itself from this monstrous attack," Schumer wrote on X.

An Israeli ground assault on Gaza was looming on Sunday after Hamas militants launched a surprise attack on Oct. 7 that killed 1,300 Israelis, most of them civilians, and took dozens of hostages back to Gaza. The Gaza Health Ministry said more than 2,300 Palestinians have been killed since the fighting erupted.

While negotiations are ongoing, Schumer earlier said he expects any spending package should include aid for Israel and Ukraine, along with possible aid for Taiwan as it faces threats from Beijing and money for the U.S. border.
