A police Investigation into last month's Jakarta hotel bombings shows that terrorist groups had made plans to use snipers to attack US president Barack Obama during his visit to Indonesia in November.

Dynno Chressbon, an intelligence analyst at the Center for Intelligence and National Security who is close to the police investigations said that two of four wanted suspects had been prepared as snipers for an attack on Obama.

Obama has been widely expected to include a stopover in the world's most populous Muslim nation, the country he spent his childhood when he attends the Asia-Pacific Economic Cooperation (APEC) summit in Singapore in November.

For Obama, they planned to attack the convoy around the airport using MK-IIIs, Dynno said, referring to a type of Russian-made sniper rifle that he said was used by the Taliban in Afghanistan and also in Muslim conflict areas in the Philippines.

The alleged snipers were from a group called the Indonesian Islamic State, which has a training camp in the restive southern Philippines and also has received support from a group headed by Malaysian-born militant Noordin Mohammad Top, Dynno said.

The terrorist group already had MK-300 gun that will be used to shoot Obama, Dynno added.
