Students in Haiti are venting their frustration at the government over classes being canceled because public school teachers are on strike in a wage dispute.

Hundreds of high school students marched near the National Palace in the capital Wednesday. Many of the students were in their school uniforms as they blocked traffic and hurled rocks at police.

Teachers have refused to show up for three consecutive class days because they have not received a wage increase approved by the government.

Education Minister Nesmy Manigat said teachers' will be going up from 30 percent to 50 percent but not until after the Senate approves a new budget.

Manigat is urging teachers to return to work, noting that national exams are just weeks away.
