WASHINGTON - A suspect in the bombing of the USS Cole and a man wanted in connection with the bombing of a 1982 Pan Am flight have been added to the U.S. government's list of "Most Wanted Terrorists," the FBI said on Tuesday.

The additions bring to 24 the number of suspects named on the roster established after the Sept. 11 attacks.

Fahd Mohammed Ahmed al-Quso is wanted for his role in the bombing of the USS Cole in Yemen, The FBI said, adding that he is believed to be 35 and may be living in Yemen.

Seventeen U.S. sailors were killed when the Navy warship was attacked in the Yemeni port of Aden in October 2000.

Husayn Muhammad al-Umari is wanted in connection with the 1982 bombing of Pan Am Flight 830, which killed a teenage passenger and wounded 16.

Al-Umari, 73, is one of three people indicted for the bombing and is alleged to have built the explosive device that was placed under a seat and detonated while the plane was en route to Hawaii from Japan carrying 267 people, the FBI said.

"A Sunni Muslim who doesn't drink or gamble, al-Umari is said to enjoy smoking Cuban cigars," according to the federal law agency's description.

A U.S. State Department program is offering up to $5 million for information leading to their capture or convictions.

A third man, Abdullah al-Rimi, also wanted for questioning in the USS Cole attack, was added to a separate list of people federal authorities want to question in connection with attacks or threats.

"We need your help to find these three individuals, all of whom should be considered armed and extremely dangerous," the statement said, advising potential tipsters to contact a local FBI office or U.S. Embassy or submit a tip electronically.
