Indonesian police killed two suspected terrorists in a raid on the outskirts of Jakarta on Friday, a force spokesman said, less than two weeks after officers shot dead five suspects on the resort island of Bali.

"The suspects tried to escape with a gun, triggering a shootout with the police who shot the two instantly," National Police spokesman Insp. Gen. Saud Usman Nasution said.

The raid took place at a rented house in Pondok Aren, South Tangerang, on the outskirts of the capital at 3:30 a.m., with anti-terror police confiscating a revolver, explosive materials, several books about jihad and documents outlining a bank robbery.

"We're still investigating whether they are linked to terror networks," the police spokesman said. "The two are also suspects in the stabbing and shooting of a traffic police officer."

The incident came less than two weeks after a counter-terrorism squad gunned down five suspects in two raids on the popular tourist island of Bali. Police suspected that group was planning a bank robbery to finance several terror attacks.

Muslim-majority Indonesia has been rocked by a series of attacks staged by regional terror network Jemaah Islamiyah in recent years, including the 2002 Bali bombings which killed 202 people.

The JI network has been weakened since anti-terror police killed some of its most prominent figures in bloody raids.
