Police hunt for Bali suspect's brothers

Police believe the two men buried explosives

Indonesian police have named two brothers of a man who admitted involvement in the attack on Bali last month as additional suspects over the bombings.

Police said that they were searching for the two men - Ali Imron and Ali Fauzi - after finding a cache of weapons hidden in East Java that the authorities believe the men buried.

Amrozi has said he once fought in an Afghan jihad

Major-General I Made Mangku Pastika, in charge of the Indonesian investigation into the Bali attack, said the men had been given the weapons by their brother and prime suspect, Amrozi.

Police say Amrozi, a mechanic, has already admitted to owning the minivan that was used in one of the 12 October blasts, and to helping to buy explosives. He was arrested on 5 November.

Weapons haul

Police found the stash of weapons which they believe were hidden by the suspects on Monday near the home of Amrozi, according to the Jakarta Post.

Kompas daily reported that the police found at least five rifles, including two M-16s as well as two FN pistols, along with ammunition, packed into six plastic pipes.

Police also said they had found TNT - used in at least one of the Bali bombs - at an apartment and hotel room in Denpasar, Bali, where Amrozi is alleged to have stayed before the attack.

Two other arrests were made on Monday. Police detained a former forest ranger known as Komarudin in Amrozi's home village of Tengallun in East Java whom they believe stored weapons and explosives for Amrozi.

They also seized Amrozi's driver, a man named Tafsir.

Jemaah Islamiah link

Many foreign governments believe Jemaah Islamiah (JI), a regional militant group believed to aspire to a pan-Asian Muslim state, was involved in the Bali attack.

That link was strengthened on Monday when police announced that Amrozi had been a student of Muslim cleric Abu Bakar Ba'asyir, the alleged spiritual leader of JI.

Police said Amrozi studied under Mr Ba'asyir in the 1990s when they both lived in Malaysia and that they had kept in contact.

Mr Ba'asyir has denied any terrorist involvement and denies being a leader of JI.

He is being detained on charges of masterminding a series of church bombings in 2000 and plotting to assassinate Megawati Sukarnoputri before she became Indonesian president.

Analysts believe that it is unlikely the powerful bombings on Bali could have been undertaken by a small local group alone.

But the BBC's correspondent in Jakarta, Jonathan Head, stresses that the Indonesian police have not made any connection between the attacks and al-Qaeda or other outsiders.

They say they are looking for a group of 10 men, all Indonesians.

Police have said that Amrozi told them his target in the bombings was American tourists.
