Anti-Israel demonstrators descended on Washington, D.C., on Wednesday ahead of Israeli Prime Minister Benjamin Netanyahu's address to Congress. 

One demonstrator, whose face was covered, was spotted by Fox News carrying what appeared to be the flag of the terrorist group Hamas. 

Fox News estimates that a few hundred protesters had gathered on Pennsylvania Avenue and 3rd Street, outside the Gallery of Art. They have a stage set up in front of the Capitol building and are currently chanting.

The protest organizers include Answer Coalition and Code Pink. There have been numerous speakers from various organizations, including one from the Party for Socialism and Liberation.

The crowds have chanted "Free Palestine" and "From the river to the sea…," an antisemitic phrase that calls for the elimination of the state of Israel.
