Photos from inside Syria's front line show rebels under attack by sniper, tank

Two Free Syrian Army soldiers take their positions on a Damascas street, waiting to move in to overtake a government checkpoint. The rebels were waiting until another group fired at the checkpoint with rockets before moving in, Tomasevic describes on his blog. (Reuters)

One rebel (right) is struck by sniper fire before he and his fellow fighters can advance, and soon dies. His comrade is hit moments later, but survives. (Reuters)

A rebel stationed across the street sneaks in to gather the body of the dead rebel and lead the wounded to safety, careful to avoid being taken out by the same sniper. (Reuters)

More rebels emerge to assist in the recovery, dragging the dead soldier and his wounded ally across the street. (Reuters)

The body of the dead soldier is then dragged inside a damaged building, away from any potential gunfire. (Reuters)

A Syrian tank follows the sniper fire with a round to the top of the building, sending rubble crashing down on the rebels. (Reuters)

The rebels run for cover as rubble continues to fall. (Reuters)

An injured soldier holds his head after the building collapses, as the rebels regroup at a nearby location. (Reuters)
