Jordan today indicted 28 Arabs linked to the suspected terrorist Osama bin Laden on charges stemming from what officials say was a conspiracy to attack Americans and Israelis during New Year's celebrations.

Fifteen of the suspects -- 13 Jordanians, one Iraqi and an Algerian -- have been in custody since December, said the attorney general, Maamoun Khassawneh.

Thirteen others, including Jordanians, Palestinians and a Yemeni, have not been found, but are possibly hiding in Pakistan, Afghanistan, Britain, Lebanon and Syria, Mr. Khassawneh said.

Jordanian officials have said those governments were contacted regarding the possible extradition of some of those suspects.
