An Indonesian court has jailed an Islamic militant for three years for having attended a meeting which plotted the deadly Marriott hotel bombing in August last year, an official said.

South Jakarta district court found Samhuri "guilty of attending several meetings" held by Jemaah Islamiyah (JI) to determine the bombing target and plan the attack, said Adi, a court official.

Eleven Indonesians, mostly hotel security guards and taxi drivers, and a Dutch banker were killed in the attack on the US-franchised hotel in Jakarta.

The Al Qaeda-linked JI staged the hotel blast as well as the October 2002 Bali nightclub bombings which killed 202 people and numerous other attacks.

Several other people are on trial, or have been jailed, for the Marriott bombing and 33 people have been sentenced for the Bali blast including three on death row.

Malaysian explosives experts Noordin Mohammad Top and Azahari Husin are still being hunted for their roles in both the Bali and Marriott attacks. Police believe they are still hiding in Indonesia.
