Two more people have been added to the FBI's "Most Wanted Terrorists" list, including a USS Cole bombing suspect and a man who is believed to be linked to a deadly Pan Am flight explosion in 1982, Reuters reported.

That brings the total number of suspects to 24. The list was established after the Sept. 11, 2001, terrorist attacks.

Fahd Mohammed Ahmed al-Quso is believed to have played a role in attacking the USS Cole in Yemen, where he may be living, according to the FBI. Their records show he is 35 years old. Seventeen American sailors died when the Navy warship was bombed in October 2000.

Husayn Muhammad al-Umari, 73, is sought for his alleged connection to the bombing of Pan Am Flight 830 in 1982, which left a teen boy dead and 16 others injured.

Federal authorities say al-Umari built the explosives that were planted under a seat and detonated during the flight from Japan to Hawaii. He is one of three indicted in the attack, Reuters reported.

"A Sunni Muslim who doesn't drink or gamble, al-Umari is said to enjoy smoking Cuban cigars," the FBI says in its description of him.

The federal government is offering a reward of up to $5 million for any information leading to the two suspects' captures or convictions, Reuters said.
