A series of bombings and subsequent gun battles yesterday between the attackers and police in a busy part of the capital lined with malls and foreign missions left two civilians and five attackers dead.
Police in the world's most populous Muslim country have blamed the carnage on a network of Islamic State fighters from Southeast Asia forged in the radical jihadist group's war in Syria and Iraq.
"An alert has been imposed throughout Indonesia," said national police spokesman Anton Charliyan.
"National police are on their highest alert, especially in areas considered targets of terror, like police stations, government offices, embassies, with army backup."
He did not elaborate on the army's role but AFP reporters saw a passing convoy of a half-dozen military trucks filled with heavily armed soldiers in central Jakarta, and heightened security elsewhere, with police patrolling in flak jackets.
A police car and a half-dozen officers were seen guarding the French embassy near the attack site.
