7:56pm: Al Jazeera Arabic is speaking to a political activist in Tripoli, who tells us there are airstrikes "all over Tripoli".
There is death, fear - and women are crying everywhere. The strikes are concentrated against areas that sent large number of protestors to the streets and there are cars full of foreign fighters firing on people.
He says at least 250 people were killed in the past 24 hours alone and is calling for international help. He tells us Tripoli is "under siege by foreign fighters" - that water and electricity have been cut and there is a shortage of food and medical supplies. "It is a genocide," he says.
7:45pm: The defected pilots reportedly tell Maltese officials they were based in Tripoli and ordered to attack protesters on the ground in Benghazi. After seeing their fellow pilots begin the airstrikes, they diverted course toward Malta. If substantiated, this would appear to confirm the use of airstrikes against civilian protesters in cities around the country.
