Tens of thousands of pro-Palestinian demonstrators marched through a rainy London on Saturday, demanding an end to Israel's bombardment of Gaza as the Israel-Hamas conflict reached its third week. Similar calls were heard in cities worldwide.

On a day when some aid trickled into Gaza, where over a million people have been displaced due to the conflict, protesters gathered at Marble Arch near London's Hyde Park before marching to Whitehall, the government district.
