Some people escaped through the windows, but there were mates who fainted inside the bus,” Castillo said.Mexican media reports that the students had to run into the bush to escape the attacks by the police and army. According to La Jornada there were 20 injuries.Other media reported multiple arrests.“This aggression is aimed at making us enemies of the people,” Castillo said, still worried about some of the students who at the time were still wandering the bush at night.“We become impotent to do anything about it, but we aren’t going to accept impunity, we don’t want more fellow students killed, we don’t want more disappearances,” he added.
