US quietly offers rewards for Benghazi attackers

The US State Department says it has been quietly offering rewards of up to USD 10 million since January for information about the attack last year on a diplomatic post in Libya.
In a letter sent to Congress today, the department says the rewards were not advertised on its website or posters as is usually done. That's because of security issues around the investigation into the attack on the mission in Benghazi that killed US Ambassador Chris Stevens and three other Americans.
Lawmakers have said the department is not using all the tools at its disposal to catch the perpetrators. The letter says investigators have other ways of publicising the rewards.

The rewards are for information that leads to the arrest or conviction of anyone involved in the attack.
