Police said seven young men were shot and wounded early Monday as they set up a roadblock as part of protests in the southern city of Jacmel.
Marc-André Cadostin, director of the southeast department of the National Police, said two of the men, ages 20 and 25, were transferred in critical condition to the capital, Port-au-Prince.
The other five men were being treated at a local hospital, he said.
Cadostin said the men were setting a barricade built across a road on fire when unknown suspects began shooting.
