JAKARTA: A sword-wielding militant killed an Indonesian policeman and critically injured another on Monday (Jun 1) in what authorities described as a terror attack by suspected Islamic State-linked extremists.
The attacker was shot dead during the early morning raid at a police post in South Daha district on Kalimantan – Indonesia's portion of Borneo island.
Indonesia's national police initially said there were two attackers, but local authorities later said only one militant was directly involved.
"One police officer was killed and the attacker also died," South Hulu Sungai police chief Dedy Eka Jaya told AFP.
"We're still investigating possible links" to Islamic State, he added.
The attacker – identified as a 19-year-old local named Abdurrahman – initially set a car on fire outside the police post, Jaya said.
"When it exploded, one of the officers came outside to check and that's when the initial attack started," he added.
Images from the scene showed an apparently deceased man lying on his back inside the police station.
Authorities said they confiscated the attacker's sword, a Quran, a handwritten letter calling for jihad and a flag bearing the tauhid – which expresses the belief in Allah as the one and only god.
Images of the black and white-lettered flag showed it resembled one commonly used by Islamic State followers.
Indonesia, the world's most populous Muslim-majority nation, has long struggled with Islamist militancy and is home to dozens of radical groups that have pledged loyalty to Islamic State's violent ideology.
Monday's violence happened on a public holiday that celebrates the Southeast Asian archipelago's pluralist democracy, and many past attacks have been against police and other state symbols.
In April, a couple with links to Islamic State went on trial for a failed assassination attempt on Indonesia's former chief security minister last year.
The pair were allegedly members of Jamaah Ansharut Daulah (JAD), an Islamic State-linked extremist group responsible for a string of attacks, including suicide bombings at churches in Indonesia's second-biggest city Surabaya in 2018 that killed a dozen people.
In November, an IS-linked suicide bomber killed himself and wounded six others in a police station attack on Sumatra island.
