The round second from right is standard 5.56mm - of the type used by NATO forces, as the photo illustrates. The round on the far left is .50 caliber and has reportedly been used against protesters. Sources in Tripoli who have spoken with doctors in the capital also said some believe explosive rounds are being used.
