JAKARTA - Police conducted raids and put up roadblocks in Depok, south of Jakarta, as Indonesians celebrated Independence Day, after two policemen were shot dead at close range on the capital's outskirts.
Officials said the policemen killed in Tangerang last Friday night were the latest targets of militants eager to hit back at the authorities for their ongoing crackdown on terrorism.
"These acts of terror have not stopped. Where before their target was foreigners, Westerners... now it has shifted," Coordinating Minister for Political, Legal and Security Affairs Djoko Suyanto told reporters on Saturday after Independence Day celebrations at the presidential palace.
"The motive has become revenge on the police because their friends have been caught."
The killings came as the police clamped down on illegal guns, and are the latest in a string of sporadic yet targeted attacks on law enforcement officers.
National Intelligence Agency chief Marciano Norman said the attacks were probably carried out by the same group involved in earlier shootings of police.
On Aug 7, an adjunct police inspector was shot dead in Ciputat, on the outskirts of Jakarta, by an unidentified man. Another adjunct inspector was shot in the chest by two motorcyclists on July 27, and survived.
Mr Marciano said law enforcement officers had to step up their guard, and the public at large had to support efforts to clamp down on unlicensed firearms.
"Today it's the police who are threatened. Tomorrow it could be others," he told reporters.
