Tear gas fired at protesters after US teen's death

Police separately arrested two journalists reporting on the unrest that has roiled Ferguson since aspiring college student Michael Brown, 18, died Saturday in a police shooting.
      
His death has triggered rioting and stirred comparisons with the February 2012 fatal shooting of unarmed teenager Trayvon Martin in Florida.
      
Wesley Lowery, a Washington Post political reporter, and Ryan Reilly, a Huffington Post reporter, were arrested in a McDonald's restaurant after police entered the restaurant and ordered people to leave, the pair wrote on Twitter.
