Indonesia has introduced tough new security measures following a devastating car-bomb attack in the capital, Jakarta.
At least 13 people, including one foreigner, have been killed while another 150 from a range of nationalities have been injured.
The blast severely damaged five floors of the luxury US-run Marriott Hotel, shattering glass and damaging cars parked outside. It is not yet clear who was behind the attack, but suspicion will inevitably fall on the group also blamed for the Bali bombings, an extremist Islamic organisation called Jemaah Islamiah.
The governor of Jakarta, Sutiyoso, said the explosion was "very likely" to have been carried out by a suicide bomber.

Tightened security
The government has ordered an immediate strengthening of its anti-terrorist laws and also invited the Australian police to help in the hunt for those responsible.
Indonesian President Megawati Sukarnoputri, who recently vowed to destroy terror networks in the world's largest Muslim nation, visited the scene of the attack late on Tuesday.
The United States urgently renewed its calls for Americans in Indonesia to follow tighter personal security measures.
Tuesday's blast came just two days before the expected verdict in the trial of a key Bali suspect, Amrozi bin Nurhasyim.

Security has been tight in Indonesia since the Bali bombings, and authorities have warned of similar threats.
