Riot police have clashed with protesters in Mexico City during a demonstration commemorating the 45th anniversary of a student massacre. Protesters, some of them masked, threw firebombs, bottles and rocks at police who battled to disperse the crowd. At least 40 people were injured, Mexico’s El Universal newspaper reported.
The rally marked the anniversary of the 1968 killings of student protesters in Tlatelolco Square. Official reports at the time said 25 people died, although rights activists say as many as 350 may have been killed.
