Former Navy SEALs died after coming to the aid of others

CNN) -- Two former Navy SEALs who were among four Americans killed last week in an attack on the U.S. Consulate in Benghazi, Libya, died after rushing to the aid of their colleagues, according to sources familiar with the incident.

Glen Doherty and Tyrone Woods were in Benghazi as part of a security contractor force.

On September 11, they were ensconced in the safety of an annex location in another part of the city when they got word that the main consulate building was under fire and the diplomats there -- with an armed force of only nine people -- were overwhelmed by the deteriorating situation.

Doherty and Woods, along with other security personnel, left the secure annex and made their way to the chaotic scene, rounding up the consulate staff who were under attack and guiding them back to the second safe building.
