Indonesian police have arrested at least 43 suspected militants in relation to an attack on a police station last week. A suicide bomber with alleged links to "Islamic State" killed himself and wounded six others.
The suicide bomber killed himself and wounded six others in a police station on Wednesday in Medan on Sumatra. The attacker has been linked to "Islamic State" (IS).
Two bomb-makers were also shot dead during a raid.
"The pair resisted arrest and tried to attack police with sharp weapons and an air gun," National Police spokesman Dedi Prasetyo told reporters in Jakarta.
He added that he believed that the suspects were a member of a local affiliate of the Islamic State group known as the Jama'ah Anshorut Daula (JAD). The arrests were made in seven provinces and included the group's leader, according to Prasetyo.
Police believe that they were responsible for making the bomb that was detonated by the 24-year-old attacker last week.
JAD has been implicated in a number of the attacks over the last two years. An Indonesian court banned the network in 2017.
In August, authorities shot and arrested a militant who attacked officers at a station in Surabaya. In June another was seriously wounded when he tried to blow himself up outside a police building on Java island.
