Libyan government tanks destroyed by Western air strikes sit at a roundabout along the coastal highway through Ajdabiyah in eastern Libya, March 30, 2011. The exact position of the front line is difficult to know in a war of rapid movements in both directions across open desert, but one constant is the presence of the road, along which Libya?s revolution has travelled, back and forth as each side advances and retreats across vast distances, leaving behind a wake of destruction and death.
