Bali, Indonesia ? Police raised the alert level for Indonesia’s capital and the president warned of more attacks Sunday as a chilling video shot the day before showed a suspected bomber clutching a backpack and strolling past diners moments before one of three suicide bombings killed 26 people on Bali.

The near-simultaneous bombings on the resort island also injured 101 people, including six Americans.

The attacks apparently were planned by Southeast Asia’s two most-wanted men, who are believed to be connected to an al-Qaida-linked group, said Maj. Gen. Ansyaad Mbai, a top Indonesian anti-terror official.

Fear of more attacks on tourists prompted Israel to warn its citizens Sunday not to travel to Egypt’s Sinai desert during the upcoming month of Jewish holidays, saying it has information that Arab militants planning strikes against Israelis already are located in the resort area.

The alleged masterminds of the Bali attacks were believed to be Azahari bin Husin and Noordin Mohamed Top, both Malaysians who fled to Indonesia after a crackdown on militants following the Sept. 11 attacks, officials said.

The masterminds were not among the suspected bombers, whose remains were found at the scenes, officials said. All three bombers were believed to be wearing belts of explosives, police said.

President Susilo Bambang Yudhoyono warned that terrorists could be planning more strikes in the world’s most populous Muslim nation as Jakarta’s police chief put the capital on top alert, with two-thirds of its police force on standby.

There were no claims of responsibility for Saturday night’s coordinated attacks on two packed seafood cafes in the Jimbaran beach resort and the Raja Cafe noodle and steakhouse in the bustling tourist center of Kuta.

Video footage shot by a vacationer at the three-story Raja Cafe captured a suspected bomber in a black T-shirt walking past foreign and local tourists eating dinner, sipping drinks and chatting at tables.

The man clutches his backpack, adjusts it slightly, then walks out of view. Moments later there is an explosion from his direction, followed by smoke and screams. Police said the video, obtained by Associated Press Television News, was part of the investigation.

Suspicion for the blasts fell on the Southeast Asian terrorist group Jemaah Islamiyah, which wants to establish an Islamic state across Southeast Asia and has been linked to Osama bin Laden’s terrorist network.

Jemaah Islamiyah has been blamed for the 2002 Bali nightclub bombings that killed 202 people, mostly foreigners.
