A series of explosions has rocked the Indonesian capital, Jakarta,with gun battles on the streets.
The blasts were centred around Thamrin Street, a major shopping and business district close to foreign embassies and the United Nations offices.
Police say the situation is now under control, with five suspected attackers among at least seven people killed.
So-called Islamic State (IS) said it carried out the attacks, a news agency linked to the militant group said.
Separately, Indonesian police said they suspected a local group allied to IS was to blame.
Indonesian President Joko Widodo described the attacks as an "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.
Images from Jakarta have shown several bodies lying on the road outside a cafe, as well as seriously injured people being carried away.
Details remain unclear, but at least one of the blasts hit a Starbucks cafe and a police security post.
It appears the gunmen then holed up in the Djakarta Theater, part of the complex that houses the Starbucks.
Armed police, snipers and armoured vehicles were deployed on the streets of the capital.
