In the US capital Washington, D.C., hundreds took part in pro-Palestinian protests on Saturday afternoon, marching from the Washington Monument to the US Capitol.
Also on Saturday, thousands of people rallied in Los Angeles in support of Palestinians. Local media said a handful of pro-Israel counterprotesters also gathered, and police officers kept the groups separated.
A demonstration that started in a neighborhood in the Bay Ridge neighborhood of Brooklyn, New York, which has a large Arabic-speaking community, continued through the streets for several hours on Saturday afternoon, said an ABC News report.
In San Francisco, a raucous crowd banged drums and yelled "Palestine will be free" as they marched across the Mission district to Dolores Park, the report said, adding that pro-Palestinian demonstrations were also held in Boston, Philadelphia, Atlanta and some other US cities.
The protests were planned for Nakba Day, which Palestinians observe every May 15 to commemorate the 1948 displacement of hundreds of thousands of Palestinians amid Israel's war of independence, local media reported.
