El Salvador's president threatens Haitian gangs over military hostages
Four members of the so-called Gang Suppression Force have been missing since Sunday.
El Salvador's president has said he has launched a military operation to rescue four air force personnel who have been missing in Haiti since Sunday.
Nayib Bukele wrote in a post on X that Wednesday's attack was "nothing" compared with what would happen if all the hostages - who he said were not combatants - were not returned alive.
They went missing after being ambushed by "heavily armed criminal groups," El Salvador's armed forces said. The ambush occurred in Croix-des-Bouquets, an area controlled by armed groups.
A statement released by the Armed Forces of El Salvador on Sunday said the group was ambushed while travelling back to its camp in an armoured vehicle, which caught fire after being hit by explosives.
