The protesters, carrying Palestinian flags, also demanded an end to the Israeli occupation of Palestinian territories.
The protest took place in line with others around the US since Israeli airstrikes targeting Gaza began on Oct. 7 in response to an attack by the Palestinian group Hamas.
To date, more than 4,400 people have been killed in the armed conflict, including at least 3,061 Palestinians and more than 1,400 Israelis.
US Secret Service has arrested many of the protesters.
