Saturday night's bomb blasts in Bali could have link with fuel oil price hikes which were felt by the people as a very heavy burden, the official news agency Antara quoted a political observer as saying.

"I think groups who are unsatisfied with the fuel oil price hike have been behind the explosions, not those who want to shift attention on fuel oil issues," Professor Budiatna, a political observer at the University of Indonesia, said in Jakarta on Saturday night.

According to Budiatna, the unsatisfied groups thought protests in the form of demonstrations were no longer effective because the government paid no attention to it.

The government increased fuel oil price hike by an average of 126 percent on Saturday.

"They pressured (the government) by resorting to terrors. Their message is to lower the fuel oil price or else the terror acts will continue," the observer added.

The former dean of the social and political science faculty said he did not believe if the terror acts were aimed to shift fuel oil reports.

Reports said that some six bombs exploded at three tourism spots of Jimbaran, Kuta Town Square and Nusa Dua in the tourist resort province of Bali.

Indonesian President Susilo Bambang Yudhoyono confirmed on Saturday night that 11 people had been killed and 27 others injured in the bombings.

On Oct. 12, 2002, bomb blasts occurred in Bali, killing 202 people, mostly Australian vacationers.
