Opposition forces claimed to control 70 percent of Zawiya, but loyalist snipers and sleeper cells remained in the city, and the rebels had not yet been able to clear them. The bulk of the pro-Gaddafi forces were reported to have retreated east towards Tripoli, though it was not immediately clear whether or not this was a strategic withdrawal. Rebels also feared a potential loyalist counteroffensive in the near future.[21] Rebel forces captured several abandoned weapons, including ammunition, anti aircraft guns and anti tank artillery.[22]
