Troops loyal to Muammar Gaddafi are pushing rebel forces back towards their heartland in eastern Libya.
The opposition fighters are being outgunned by Gaddafi’s superior military firepower and are at risk of being forced to retreat to their stronghold, Benghazi.
Gaddafi’s forces are advancing steadily eastwards, retaking towns such as Ajdabiyah and Brega, which were captured by rebels in the early days of the uprising.
But the leader of the opposition forces remains defiant.
Colonel Ahmed Baha Eddine told Euronews his troops are gearing up for a major assault on the town of Sirte, Gaddafi’s birthplace, which they plan to use as a staging post for an attack on Tripoli.
In most places, though, it is still a case of advance and retreat.
