Three Haitian police officers and two civilians were killed Wednesday in the country’s central region amid a surge in gang violence, officials and a police union reported.

The fallen officers belonged to UDMO, a specialized unit typically deployed to manage protests and unrest.

A video circulating on social media shows gunmen dragging the bodies of at least two officers near a burning armored vehicle as intense gunfire echoes in the background.

SPNH-17, a local police union, said two “brave citizens” fighting alongside the slain officers in Artibonite also were killed.

The union called on the government to better protect police and warned officers were preparing to revolt.
