I was in Pointe-Noir two days ago. Customers (pax on our aircraft) told us that Air France sent another (larger) B777 to rescue the situation and that some of their group had travelled out on that one. It was also reported (by our handling agent there) that the altercation occurred when an airport gendarme (whom apparently was intoxicated) approached the parked Air France aircraft but was told to "piss off" (or words to that effect) by independent security contractors whom had been tasked with guarding it. Somewhat aggrieved at being rebuffed, monsieur gendarme then lost the plot, fired off some rounds, the result of which can be seen in the pictures.
