Bomb blasts rocked at least two hotels in the Indonesian capital, Jakarta, Friday morning, killing at least six people, including foreigners, according to media reports quoting police.
Reports said the facade of the Ritz-Carlton hotel was blown off in one blast while another explosion hit the nearby Marriott hotel. A witness said the explosions happened within five minutes of each other around 7:30 a.m. local time.
A Jakarta hospital doctor said 18 were injured.
An Associated Press reporter saw three injured people taken away from the Ritz. Video footage of the scene outside the Marriott showed ambulances streaming to the hotel as dozens of police and security guards cordoned off the area.
There were no immediate claims of responsibility for the blasts.
The country held an election last week, in which incumbent President Susilo Bambang Yudhoyono was declared the winner. Despite allegations of electoral fraud by Yudhoyono's opponents, independent observers declared the election largely free and fair.
Jemaah Islamiyah, a militant Islamic organization, has been blamed for a series of attacks between 2002 and 2005 that killed more than 240 people, most of them foreign tourists on the island of Bali.
The group was blamed for a previous blast at the Jakarta Marriott in 2003 that killed 12 people.
