Indonesia’s security forces in the battle in the remote mountain jungles have eliminated the most wanted militant with ties to the Islamic State group, informed the country's military.

Mr. Ali Kalora was one of two militants killed in the raid, said Central Sulawesi’s regional military chief Brig. Gen. Farid Makruf. He identified the other suspected extremist as Jaka Ramadan.

The two men were fatally shot late Saturday by a joint team of military and police officers in Central Sulawesi province’s mountainous Parigi Moutong district, Makruf said. It borders Poso district, considered an extremist hotbed in the province.

Ali Kalora was the most wanted terrorist and leader of MIT, Mr. Makruf said, referring to the Indonesian acronym of the East Indonesia Mujahideen network, a militant group that pledged allegiance to the Islamic State in 2014.

He said that security forces were searching for four remaining suspected members of the group.

Saturday’s shootout occurred two months after security forces killed two suspected members of the group during a pre-dawn raid in the same mountainous district.

The East Indonesia Mujahideen has claimed responsibility for several killings of police officers and minority Christians.
