Riot police and protesters have clashed in the Honduran capital, Tegucigalpa, during protests against planned reforms of the health and education sector.
Hundreds of people had to be evacuated from a number of buildings in the city after they were set alight.
The protesters fear that the reforms could lead to mass lay-offs of teachers and doctors.
They have been on strike since Congress approved the reforms. Demonstrations were also held outside the capital.
A largely peaceful march against the reforms turned violent when a small group of hooded protesters clashed with riot police in the historic city centre of Tegucigalpa.

Police evacuated more than 250 people from the city hall after it was set alight by demonstrators throwing petrol bombs.
