Along The Libya-Tunisia Border (CNN) -- A green flag fluttering in the wind designated Libyan territory. A short distance away, a red flag flew for Tunisia. In between, a mass of humanity waited in no man's land, desperate to flee escalating rebellion in one nation and cross into another that has already succeeded in toppling a dictator. Periodically, a ripple flowed through the crowd of thousands of refugees as men took turns passing forward dazed and unconscious travelers, overwhelmed by a treacherous journey to the border and exposure to the elements. Tunisian emergency workers rushed with fluorescent orange stretchers to evacuate the sick.
