Protesters demonstrating against Prime Minister Benjamin Netanyahu's visit to Washington and against US aid to Israel held a sit-in protest at congressional offices on Tuesday, international media reported.
Hundreds of protesters took over the rotunda of the Cannon Building, which holds the offices of House of Representatives members.
The demonstrators wore red T-shirts bearing the phrases "not in our name" and "Jews say stop arming Israel." Some carried banners reading "ceasefire now" and "let Gaza live."
Arrests made during the protests
The protests were reportedly organized by Jewish Voices for Peace.
Police have begun making arrests.
"For the past 9 months, we've witnessed countless horrors in Gaza, committed in our names and funded by our government," Jewish Voice for Peace wrote on social media.
It said over 250 protesters were arrested and that there were 400 demonstrators in attendance.
Police did not immediately give arrest figures. A police statement said: "We told the people, who legally entered, to stop or they would be arrested. They did not stop, so we are arresting them."
This is a developing story.
