Indonesia's counter-terrorism forces have shot dead one suspected militant and made a series of arrests following the Surabaya suicide attacks.
Indonesian police have fatally shot a militant and arrested 13 people with suspected links to suicide bombings carried out by two families in the country's second-largest city.
Surabaya police spokesman Frans Barung Mangera said the militant died in a shootout in a Surabaya neighborhood with counter-terrorism police, who had tried to arrest him over possible involvement in the attacks that killed at least 12 people.
He said raids in Surabaya and its neighbouring cities of Malang and Pasuruan resulted in 13 arrests.
Coordinated suicide bombings at three churches were carried out Sunday by a family of six that included girls aged 8 and 12.
A second family bombed Surabaya's police headquarters on Monday. Their seven-year-old daughter survived the attack.
Twenty five people died in the two days of attacks including a total of 13 militants and their children.
The Islamic State group claimed responsibility for all the attacks in statements carried by its Aamaq news agency.
Earlier Tuesday, police searched the home of the family that bombed Surabaya's police headquarters.
