A student affected by tear gas is helped during clashes between students and the national police in Port-au-Prince, Haiti, Wednesday, May 7, 2014. Students are protesting to demand authorities respond to their striking teachers' demands for higher pay and improved working conditions. Students are concerned they will not be able to take exams which allow them to move on to the next level. Public school teachers across Haiti have been on strike for one week.
