Personnel of a joint-task force have shot dead one member of IS linked group in exchange of fire with the group in Central Sulawesi province of Indonesia and arrested another militant, the police said here on Monday.

Indonesian police and soldiers grouped in the task force have been launching a military operation against the members of Mujahidin Indonesia Timur (MTI), which has been loyal to the IS terrorist group and committed a series of terrorist strikes in the area. The group has rejected a police ultimatum to surrender on Jan. 29.

During the exchange of fire, Basyir alias Ramzi was killed and his terrorist fellow Aditya alias Idad or Kuasa was captured, assistant of operation for the national police chief Inspector General Rudi Sufahriadi said.

"Basyir alias Ramzi had been included in the list of those hunted. He had not been at large since 2012," he said at the national police headquarters.

During the crackdown, a long rifle of M16 was seized, the police officer cited.

On Dec. 31, of last year, the militant group shot 2 police personnel who were trying to evacuate a body of a civilian believed to be killed by the members of the group, according to the police.
