The State Department says it has been quietly offering rewards since January of up to $10 million for information about the attack last year on a U.S. diplomatic post in Libya.
Three men with ties to San Diego were killed in the attack on the U.S. consulate in Benghazi on Sept. 11, 2012.
They include Information Management Officer Sean Smith of Clairemont, former U.S. Navy SEAL Tyrone Woods, of Imperial Beach, and former U.S. Navy SEAL Glenn Doherty of Encinitas.
The men died alongside U.S. Ambassador Chris Stevens.
In a letter sent to Congress Friday, the department says the rewards were not advertised on its website or posters or matchbooks as is usually done. The letter says investigators have other ways of publicizing the rewards.
The rewards are for information that leads to the arrest or conviction of anyone involved in the attack.
