A series of bomb blasts have rocked the Indonesian capital, Jakarta, with continuing gunfire and reports of further explosions.
At least six people have been killed by the blasts, say police, which hit locations including a shopping centre close to UN offices, the BBC reports.
Police say at least four suspected attackers are dead. It remains unclear who was behind the assault.
President Joko Widodo has called for calm but condemned the “act of terror”.
“We all are grieving for the fallen victims of this incident, but we also condemn the act that has disturbed the security and peace and spread terror among our people,” he said.
