Roughly one million people - including leaders from around the world - today joined a march described as "a cry for freedom" to honor those killed in this week's terror attacks in Paris.
The march began at 3 p.m. (9 a.m. ET) at the Place de la Republique, near the Charlie Hebdo offices. It will then break up into three marches -- one down Boulevard Voltaire, one down Rue Bastille, and the third down Rue Philippe Auguste.
