Nato planes start watch on Libya
Nato has started round-the-clock surveillance of the air space over Libya, where government jets have been pounding rebel positions.
The first airborne warning and control plane went on patrol at 6:30am Irish time this morning.
A Nato official says each of the Boeing E-3 Sentry aircraft will remain over the Mediterranean for eight hours before being replaced by another plane.
Nato has 17 E-3s. Several planes are currently operating over Afghanistan. The entire fleet is registered in Luxembourg, a country without an air force.
The alliance decided on Monday to provide the surveillance.
