Baghdad, 21 July (AKI) - Iraqi authorities announced Friday the arrest of 19 terrror suspects who were allegedly preparing to attack a police station. At least one of those arrested may be linked to a series of car hijacking attacks in the city Sabaa al-Bur, west of the capital Baghdad, authorities said. "One of the suspects confessed he hijacked model Kia cars on the road to Najaf after killing the passengers," authorities said. Last month gunmen took several South Korean-made Kia from pilgrims travelling to a Shiite religious site in Sabaa al-Bur. No trace of the cars' original occupants has been found.
