The BBC reported that Jordanian security forces said they had killed four gunmen after flushing them out of the castle.
A female Canadian tourist, two Jordanian civilians and seven security personnel, were shot and killed when several gunmen holed up in a Crusader-era castle in the southern Jordanian city of Karak engaged in a shootout with security forces.
The BBC reported that Jordanian security forces said they had killed four gunmen after flushing them out of the castle.
Police said suicide belts and weapons had been seized at a hideout used by the "terrorist outlaws".
At least 29 people were taken to hospital, some with serious injuries, security sources said.
Reuters speculated that the gunmen could have been tribal outlaws with a vengeance against the state rather than Islamic State fighters, who control parts of neighbouring Syria and Iraq.
“When we are in a region engulfed with fire from every side you expect that such events happen," a government official said.
