Protesters clashed with police on Monday in Port-au-Prince while a general strike kept most people at home across the country in a fourth day of unrest sparked by a now-rescinded government plan to raise fuel prices.
Demonstrators linked to various opposition factions marched on the parliament building but were turned back by police. Protesters also set fire to a tax office in the Tabarre area of the capital.
But much of Port-au-Prince and the country shut down.
The general strike halted the mini-buses and taxis that most Haitians depend on to get to work or school.
Most businesses closed after the people took advantage of the protests to loot shops around the capital.
Public Security Secretary Ronsard Saint Cyr and leaders of the House of Deputies and Senate called for an end to the protests and to the general strike.
