THREE Bali bombers have been executed by firing squad on their prison island in Indonesia, according to television station TV One.

Islamic militants Mukhlas, his younger brother Amrozi, and Imam Samudra were put to death for their lead roles in the 2002 Bali nightclub bombings.

A prison source confirmed the executions in a one-word SMS to an AAP stringer at Cilacap, near Nusakambang.

The SMS said: “sudah” (already).

The attacks killed 202 people, including 88 Australians.

Hundreds more were injured when bombs tore through the crowded Sari Club and nearby Paddy’s Bar on October 12, 2002. AAP
