(Adds details of protest)
Protesters calling for a ceasefire in the Israel-Hamas war on Thursday blocked the San Francisco Bay Bridge, a key commuter route into the city which is hosting the Asia Pacific Economic Cooperation (APEC) forum.
Organizers said 200 people attended the demonstration, which also called for an end to U.S. military aid to Israel. Police had arrived and formed at least one riot line, according to a social media post from one of the organizers.
Local emergency services warned of the blockage during morning rush hour on the bridge which links Oakland and other East Bay cities to San Francisco.
Multiple social media posts showed protesters had formed a human chain linked together through vehicles adorned with signs that said "Free Palestine" among others.
Several protesters appeared to be lying on the asphalt covered with white sheets.
