Indonesia's president says terrorism is blackening the country's image worldwide

Indonesian President Susilo Bambang Yudhoyono said Wednesday that deadly bombings on tourist-packed restaurants in Bali and other terror strikes were battering Indonesia's reputation and called on his military to stamp out the scourge of terrorism in the world's most populous Muslim nation.

Investigators were analyzing bomb scraps pellets, batteries, cables and detonators found at the scene of Saturday's triple suicide attacks and renewed calls for anyone who recognized grisly photographs of the three bombers to step forward.

Dozens of people have been questioned, almost all of them witnesses, but police said it was too early to say who masterminded the terrorist attack Indonesia's fourth in as many years.

"The terrorist acts have spoiled Indonesia's reputation in the eyes of the world," said president during a speech marking the 60th anniversary of the birth of the country's military.

He called on the armed forces to "take a technical and strategic role in fighting and preventing future attacks."

Southeast Asian nations have gone on high alert to prevent a repeat of the Saturday night bombings on the popular resort island of Bali that killed 22 people, putting hundreds of thousands of troops on standby, tightening security on beaches, and stepping up border security.

On Bali itself, shops put up shatterproof glass and some hotels were hiring one security guard for every 10 rooms. Police are on the streets and at the airport in force, and officials say searches and metal detector screenings will become even more common.

"Bags will be checked. Cars will be checked. This is an inconvenience, but it is for safety reasons," Indonesia's Tourism Minister Wacik said. "The world community has become more immune to bombs going off. London and Madrid recovered, and we will recover,” reports the AP.
