Indonesian police shot dead a suspected militant linked to the Islamic State (IS) group during a firefight at a government office Monday after a small bomb was set off nearby.

Witnesses described terrifying scenes as the attacker stormed into the building brandishing a dagger and began yelling at staff and starting fires. TV footage showed heavily armed police firing on the office through clouds of smoke.

No one apart from the attacker was hurt in the incident in the city of Bandung on Java island.
