The use of backpack bombs in the Saturday's attack on Bali, instead of the usual car bombs used in a string of major bombings in Indonesia since 2000, has raised allegation that a new terror group has emerged in the country.

"This can be a new group given the use of backpack bombs," national police spokesman Insp. Gen. Aryanto Boedihardjo told a press conference at the police headquarters here.

The previous bombings, from the Jakarta Stock Exchange building in 2000 to the Australian Embassy compound last year, used cars loaded with explosives.

Aryanto said the group who carried out the latest bombings in Bali may be different from the one led by two Malaysian fugitives Azahari Husin and Noordin Moh Top, who are widely blamed for the attacks on Bali in 2002, on the Marriott Hotel here in 2003 and on the Australian Embassy compound last year.

Police believed the Saturday's bombings in Bali were carried out by suicide bombers carrying explosives of less than 10 kg each planted in their backpacks.

Three severed heads found near the scene were believed to be the bombers and the photographs of the identifiable heads have been circulated nationwide through newspapers.

But no one appears to recognize them so far.
