French troops took over patrols Sunday in Port-au-Prince slum where U.S. marines had earlier killed at least two people. Meanwhile, not far from the center of the city, Canadian troops are setting up a command post for their mission.

The U.S. soldiers reported they had come under fire Friday in La Saline, a seaside slum, although no weapons were found after the incident.

Residents were angry, and said the men who were killed were not militants and were not armed.

French soldiers believe taking over patrols in La Saline could help cool tempers. The French have a better ability to communicate with the Haitians, who speak mainly French or Creole.

Meanwhile the top U.S. general, Richard Myers, visited Haiti over the weekend and warned that the international force will not tolerate brutality against troops or civilians. "Those causing violence will be dealt with appropriately.''

Later in the week, 450 Canadian soldiers will join the U.S.-led force to restore security and stability to Haiti. Already, an advance team is setting up the unit.

The Canadians will join the U.S. and French troops in Port-au-Prince, and U.S. marine Maj. Richard Crusan said the patrols could eventually extend outside the city.

Canadian troops may also eventually help facilitate the movement of desperately needed aid. The flow of aid stopped when the recent crisis in Haiti began in early February.

Quebec priest Raymond Pearson, who runs an orphanage in the capital, is totally dependent on humanitarian assistance and is hoping it will soon be restored. Meals at the orphanage now consist of little more than rice and beans.

For now, the international mission is primarily concerned with security, and is trying to disarm the militant supporters of former president Jean-Bertrand Artistide, who have been responsible for much of the recent violence.

Aristide left Haiti Feb. 29 under pressure from a month-long rebellion, and later claimed the U.S. had forced him to leave.

There are concerns that tensions could increase again, with news that Aristide is on his way back from Africa to the Caribbean to meet with his family in Jamaica.

Aristide has been warned not use the neighbouring island as a platform to return to power.
