PARIS — Hundreds of thousands of people poured into the streets of Paris to join top French officials and world leaders for a rally and march under extraordinary security in a government-sponsored show of unity and defiance after a series of terrorist attacks.
The somber march began shortly after 3 p.m., with a vanguard of dark-coated leaders marching arm-in-arm down the broad Boulevard Voltaire. Familes of the victims walked grim-faced, some wearing Charlie Hebdo headbands to commemorate the journalists murdered on Wednesday.
