Hawzah News Agency (Tehran, Iran) - In his message, Bahram Qasemi sympathized with the bereaved families of the victims of the deadly attack.

According to Reuters, on Friday, terrorists detonated a homemade device planted under a police van parked near a music festival in the predominantly Christian town of Fuheis, just west of the capital Amman. The blast, which no group has claimed responsibility for, killed one policeman and injured six others. 

Jordanian authorities organized a massive security operation the following day. Evidence led them to the hillside city of Al Salt, about 15 minutes from Fuheis. Security forces zeroed in on a multi-story building in a busy residential quarter of the city where they believed the attackers were holed up. 

When security personnel attempted to storm the complex on Saturday night, the suspects opened fire and set off powerful explosives, Jordanian officials said. The explosives, one of which was possibly a blast from a suicide bomber, caused the collapse of one side of the building. 

A hail of bullets exchanged between the suspects and security personnel injured at least 20 people in the area, including women and children who were taken to a hospital in Amman, a medical source confirmed.
