100,000 march in London in solidarity with Gaza
About 100,000 protestors from across Britain have rallied in London to protest against Israel's onslaught on Gaza, according to demonstration organizers Stop the War coalition.
Demonstrators of mixed ethnicities, race and color from across Britain including grandmothers and children, Jews and Muslims, began their march from Downing Street on Saturday amid bright sunshine.
Protestors chanted: "David Cameron shame on you!" and "Free Palestine!" as they marched under the watch of police officers lining the streets and hovering in helicopters in the skies above the British capital.
As the march started, about 10 members of London's Hasidic Jewish community posed beneath a banner emblazoned with anti-apartheid revolutionary Nelson Mandela's words: "South Africans cannot feel free until the Palestinians are free."
Stop the War rally organizer Lindsey German told the crowds: "We will demonstrate until Gaza is free," as she stood on a stage outside the Israeli embassy.
