Italian Foreign Minister Franco Frattini has called for an immediate halt to hostilities in Libya to allow humanitarian aid to reach the population in the strife-torn country.
Frattini called for "an immediate humanitarian suspension of hostilities" in Libya during a speech to the lower house of parliament.
"With regard to NATO, it is fair to ask for increasingly detailed information on results as well as precise guidelines on the dramatic errors involving civilians," he added.
The call came days after NATO acknowledged the accidental killing of civilians in a Tripoli bombing for the first time on Sunday.
NATO admitted to misfiring in an air strike that Libyan authorities said left nine dead, including two children.
The 28-nation alliance also acknowledged striking a military target in the Sorman area west of the capital which the regime said had killed 15 people, including three children.
Frattini had warned in Luxembourg Monday that NATO's accidental killing of civilians in the Libyan air war was endangering the alliance's credibility.
