Port-au-Prince, Haiti ? Gunmen killed two Jordanian U.N. peacekeepers and seriously wounded a third Tuesday at a checkpoint in a slum in Haiti’s capital that is a stronghold for supporters of former president Jean-Bertrand Aristide, a spokesman said.

The shootings in the teeming slum of Cite Soleil in Port-au-Prince occurred three weeks before long-postponed elections to replace the interim government imposed after Aristide fled the country.

The three Jordanian peacekeepers were patrolling the checkpoint when they came under fire, U.N. spokesman Stephane Dujarric said.

One was apparently killed instantly while the other two were taken to a hospital where one died of his wounds. The other was listed in serious condition, he said.

The Feb. 7 elections have been repeatedly postponed because of logistical and security problems in the Western Hemisphere’s poorest nation.
