Video: Protesters pepper-sprayed by SFPD at 'Hands Off Rafah' demonstration

SAN FRANCISCO - Protests in support of Palestine have popped up in dozens of cities across the country, including here in the Bay Area. 

Hundreds of protesters flocked to Embarcadero Plaza Saturday in San Francisco as part of a worldwide "Hands Off Rafah" demonstration.

The Market Street gathering was led by the Arab Resource and Organizing Center.

Signs expressed support for the Palestinian people and called for the end of U.S. aid to Israel's military. At one point, a protester pulled down the American flag flying on a nearby pole.

Earlier Saturday, the U.S. delivered humanitarian aid to Gaza, but protesters say the president needs to take more action.

At times, protesters clashed with police officers. At one point, an officer could be seen pepper-spraying demonstrators. AROC says several protesters are suffering from serious injuries, including broken hands.

KTVU has reached out to San Francisco police on this matter and is awaiting comment.
