Haiti ? Four people were shot to death Wednesday and Thursday in the latest surge of violence in Haiti’s largest slum.

The three men and a woman were killed Wednesday night and early Thursday in the Port-au-Prince slum of Cite Soleil, authorities at St. Catherine Hospital said. Seven others were injured.

Residents blamed the killings on Jordanian peacekeepers who they said sprayed the area’s cinderblock homes with bullets from high-powered weapons. U.N. spokesman Damian Onses-Cardona said he had no report on any troop offensives in Cite Soleil since Tuesday and said peacekeepers didn’t open fire unless attacked.

The 9,000-strong U.N. force is struggling to restore order ahead of the country’s repeatedly postponed elections, now set for Feb. 7, and has clashed often with well-armed street gangs blamed for kidnappings and killings.

More than 1,500 people – including 78 police officers and nine U.N. peacekeepers – have died since former President Jean-Bertrand Aristide fled Haiti in February 2004.
