Indonesia's Attorney General's office has asked the country's central bank to freeze the assets of companies that may be linked to suspected terrorist Osama bin Laden. A spokesman for Indonesia's Attorney General's office says the office sent a letter to Bank Indonesia to freeze the assets of 28 companies. Officials will not disclosed the names of the companies, but do say they are not necessarily Indonesian firms. The United Nations Security Council passed a resolution calling for the freezing of suspected terrorist assets following the September 11 attacks on New York and Washington. The U.S. government sent a list of 26 international terrorist organizations to a number of allied countries, including Indonesia. The U.S. asks that its allies in the fight against terrorism investigate the groups. The list includes Osama bin Laden's al Qaeda, and the Abu Sayyaf, a guerrilla movement in the southern Philippines. Analysts think the Abu Sayyaf is linked to a bombing last year in the Indonesian capital. The car carrying the Philippine ambassador in Indonesia was blown up, killing two people. The question of whether Abu Sayyaf has any financial links in Indonesia has yet to be answered. Indonesian President Megawati Sukarnoputri promised to support Washington's efforts to stamp out worldwide terrorist groups. But she has criticized the U.S.-led airstrikes in Afghanistan. She also has demanded that the air strikes be halted during the Islamic holy month of Ramadan.
