JAKARTA, INDONESIA—Authorities on Tuesday traced a blast that killed 15 people at a Jakarta hotel to a Toyota minivan that was turned into a powerful car bomb, and said they had recovered the hands of a man who may have been a suicide bomber.
The bomb ripped through the lobby of the JW Marriott Hotel, a crowded ground floor restaurant and the entryway of an adjoining office building at lunchtime, shattering windows, setting cars on fire and sending smoke billowing into the air. About 150 people were injured.
Police disclosed today that they had known since last month that the Jemaah Islamiah terrorist network was targeting the area including the Marriott.
Authorities increased security patrols in the neighborhood and issued a general warning, but they did not specifically alert the public to the danger at the hotel.
Authorities learned of plans to attack the hotel when they arrested nine suspected Jemaah Islamiah members last month. Police also seized a large quantity of explosives and documents detailing some of the group's plans.
"There was a warning that there were some targets, and we have been anticipating an attack," said Jakarta police spokesman Prasetyo, who, like many Indonesians, uses only one name.
"One of the targets was where the Marriott was located."
There was no immediate claim of responsibility for the bombing, the second major attack in Indonesia in 10 months. Authorities had warned in recent weeks that Jemaah Islamiah, a Southeast Asian extremist group with ties to Osama bin Laden's Al Qaeda terrorist network, was planning new attacks.
The bombing of two Bali nightclubs in October killed 202 people and prompted Indonesia to begin cracking down on Islamic militants, particularly Jemaah Islamiah, which is believed to have been responsible for the Bali attack.
Indonesian Police Chief Dai Bachtiar said Tuesday's bomb, concealed in a Toyota Kijang van, resembled the car bomb used in Bali, in part because of its tremendous force.
He said police were investigating whether fugitives in the Bali case were involved in the hotel explosion.
"The Kijang car that carried the bomb was totally destroyed, leaving the car frame while the engine was thrown free," Bachtiar said. "This condition is very similar to the Bali bomb."
Prasetyo said a Marriott security guard who was injured in the blast saw a man in the Kijang moments before the explosion.
"Near the car, there were a lot of human body parts," Prasetyo said. "We are examining whether the body parts came from the Kijang driver."
Police said they hoped to take fingerprints from the hands of the suspected suicide bomber to help identify him.
Police also said they believe they found the head of the driver on the third floor of the adjacent Mutiara Plaza office building.
The blast broke windows as high as the 30th floor of the 33-story hotel and sent shards of glass flying. Nearly two dozen cars were destroyed.
Hours later, blood from the victims was visible on the ground as far as 100 yards from the hotel.
