At least 10 people were killed on Sunday when gunmen in Karak, Jordan, opened fire at a popular tourist attraction. As many as 10 gunmen then barricaded themselves inside the Karak Crusader castle with 14 hostages believed to be mostly foreign tourists. The hostages have reportedly been freed. Those killed in the attack included four police officers, two Jordanians and a Canadian tourist. At least 20 others were injured. Residents began to flee the city almost immediately when Jordanian special forces were trying to free the hostages. A source told The Washington Post that the gunmen are likely affiliated with al Qaeda or ISIS.
