At least 100,000 pro-Palestine marchers, including Julian Assange, the former foreign minister Bob Carr and the government MP Ed Husic, have marched across Sydney Harbour Bridge in the rain to protest against Israel's conduct in Gaza and to speak out about the children starving there.

The world-famous landmark was closed to traffic at 11.30am on Sunday, with protesters gathering in Lang Park in the city centre before enduring heavy rain as they walked across the bridge.
