The African Union (AU) called on NATO to stop targeting Libyan officials in their air raids, after NATO forces on Monday bombarded an office of Libyan Leader Muammer Gaddafi in the capital Tripoli, reported Al-Arabiya news channel on Wednesday.

On Tuesday, Libya urged the pan-African body to hold an emergency summit in order to discuss means of facing the Western airstrikes.

In the meantime, representatives of 61 tribes from across the North African country affirmed they want to "establish a unified Libya after Gaddafi steps down."

The tribes' remarks came in a joint statement they issued on Tuesday.
