JAKARTA, Indonesia (CNN) -- Indonesian authorities believe two suicide bombers checked into the JW Marriott Hotel in Jakarta and carried out coordinated bombings Friday morning, killing themselves and at least six victims and wounding more than 50 others. A body is removed following the blasts at the Ritz-Carlton and the nearby J.W. Marriott hotels in Jakarta on Friday. It is unclear what group is behind the attacks on the Marriott and the adjacent Ritz-Carlton hotel, Indonesia's National Police Chief Gen. Bambang Hendarso said at a news conference. He warned that the death toll could rise. Four of the six victims in Jakarta's hotel bombings were foreigners, the Indonesian Healthy Ministry said Saturday.
