The body of Indonesia’s most wanted militant with ties to the Islamic State group and a follower, who were killed in a jungle shootout with security forces, were evacuated early Sunday to a police hospital for further investigation, police said.

The military earlier said the militants killed late Saturday were Ali Kalora, leader of the East Indonesia Mujahideen network that has claimed several killings of police officers and minority Christians, and another suspected extremist, Jaka Ramadan, also known as Ikrima.

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

Several pictures obtained by The Associated Press from authorities showed an M16 rifle and backpacks laid near their bloodied bodies. The Central Sulawesi Police Chief Rudy Sufahriadi told a news conference on Sunday that security forces also seized two ready-to-use bombs from their backpacks, which also contained food and camping tools.

He said the bodies of Kalora and his follower have been evacuated to a police hospital in Palu, the provincial capital, after the rugged terrain and darkness hampered earlier evacuation efforts from the scene of the shootout in the forested village of Astina.

“We urged the other four wanted terrorists to immediately surrender and dare to take responsibility for their actions before the law,” said Sufahriadi, referring to remaining members of the East Indonesia Mujahideen who are still at large in the jungle on Sulawesi island.
