A number of pro-Palestinian protesters were apprehended by U.S. Capitol Police officers as they staged a protest inside one of the House office buildings just one day before Israeli Prime Minister Benjamin Netanyahu is slated to address Congress.

Protesters gathered in the rotunda of the Cannon Office Building on Tuesday afternoon, their chants echoing throughout the building that were heard from several floors away. Capitol Police attempted to disperse the crowd and confiscate banners, although it was not immediately clear how many protesters were arrested.

Protesters, donned with red t-shirts that read “Jews Say Stop Arming Israel,” sat on the floor and linked arms as they chanted “Free Palestine.”

There have been several demonstrations inside Capitol office buildings related to the war in Gaza, with protesters often urging lawmakers to call for a ceasefire. Groups have previously interrupted press conferences and other congressional hearings demanding a ceasefire in Gaza.

The Washington Examiner contacted the U.S. Capitol Police for more information.
