The Presidency Council has attempted to seize control of the main border point between Libya and Tunisia from the Amazigh, or Berber, tribe that has held it since the revolution. The western military command, led by former Defence Minister Usama Juwaili, moved tanks and heavy artillery into the area at the end of last week and there is now an uneasy stand-off during the high-level negotiations.
Control of the border with its many smuggling routes, vital both for security and the economy, was one of our key concerns in 2011. See Chapter 6 of Belfast to Benghazi for an assessment of the tribal rivalry and strategic risks in the North West of Libya.
