I've been following live feeds for several hours, events are unfolding very radipdly. Here are some highlights:

"Tripoli security forces seem to have gone into meldown - they don't know if they are supposed to be supressing the citizens or protecting key sites or preventing ff entering the city and don't know which of their units remain loyal and which have switched sides or just plain melted away. Look to have been taken totally off guard while the TNC had this planned all along.

Result is patchy resistance but no cohesive action, as a result they are being overwhelmed despite all their heavy weaponry. Hopefully this will be over soon with the sheer momentum of events sweeping the last bastions of government security aside - please!"
