I missed the fighting in Tripoli on Saturday but on Sunday, myself and colleagues Josh Wood and Zak Brophy went to sift through (almost still smoldering) the rubble. We saw residential apartments in both neighbourhoods that had been wrecked by RPG/Energa fire, with people from both sides claiming that the other was entirely to blame.
This scenario is old news here, these neighbourhoods have been fighting for years. However, the current conflict in Syria has given them yet another reason to have at it, and sadly, likely the the funds to do so too. During the Civil War Lebanon was a sandpit in which the world waged its wars; it'll be a sad day if this becomes the case again.
