More than a million people and dozens of world leaders were expected to march through Paris on Sunday in a historic display of global defiance against extremism after Islamist attacks that left 17 dead. In an unprecedented show of unity, the leaders of Israel and the Palestinian Authority will both attend the rally to honour the victims of three days of bloodshed that claimed the lives of both Jews and a Muslim police officer. Security was beefed up as the City of Light reeled from the Islamist attacks on the Charlie Hebdo satirical magazine and a Jewish supermarket, with thousands of extra troops and police deployed to guard the march and snipers positioned along the route.
