Militants and troops killed
Jordanian search teams have pulled three bodies of militants from the rubble of their hideout, a government official said.
The search came hours after assailants opened fire and set off explosions that killed four members of the security forces trying to storm the building.
The clash raised new concerns about attempts by domestic and foreign militants to carry out attacks and destabilise the pro-Western kingdom.
The chain of events in Jordan began on Friday when assailants detonated a home-made bomb under a police car in the town of Fuheis.
The blast, deemed a terrorist attack, killed a police officer.
Security forces chasing the suspects zeroed in on a multi-story building in the town of Salt, near Fuheis, and attempted to storm it late on Saturday.
The suspects holed up inside opened fire and set off powerful explosions, officials said.
A government spokeswoman said three members of the security forces were killed.
She said on Sunday that a fourth officer had died and that the bodies of three suspects were pulled from the rubble. Five suspects are in custody.
The side of the building collapsed after the explosions
