At least three people have been killed in a series of blasts in the Indonesian capital, Jakarta, with reports of ongoing gunfire.
The blasts happened outside the Sarinah shopping centre, near the presidential palace and UN offices, say reports.
A BBC reporter at the scene said police have cordoned off the area. He said they were occasionally taking cover behind cars.
There is no indication yet of who might be behind the assault.
Indonesia has been attacked by Islamist militant groups in the past and has been on high alert.
