Water no doubt from broken storm sewer- due to NATO bombing. However, many claims being made that forces of New Libya are diverting sea water into the tunnel complex(s) under Sirte itself. Reports of water coming up/out of entrance ways and air shafts to these tunnels.
Ah, flooding the tunnels. That would force the Gaddafi rats to the surface wouldn’t it. Tunnels have definitely been used in the past in warfare.
