Tripoli, Dec 2 (IANS): A Libyan national army warplane Tuesday bombed an ammunition depot in an Islamist militants-controlled area, according to a military source.

The source told Xinhua that a MiG-21 fighter carried out an airstrike against an ammunition storage site in the town of Zuwarah, some 120 km west of capital Tripoli. There were no casualties.

"The site was a source of ammunition supply for the Islamist armed alliance Libya Dawn. It is a vital and important strategic location for them. We were able to destroy it," the source added.

The information office of Libya Dawn claimed that the site is used for food supply.

The Libyan army had earlier warned citizens not to approach sites of Libya Dawn militias as they might be targeted by the army warplanes.

In November army jets carried out airstrikes in several cities including Tripoli, Zuwarah, Zawiya, Sorman and Gharyan, which are all under the control of Libya Dawn.

Libya's national army, along with some pro-secular militia, has engaged in several battles since mid-November trying to regain control of lost cities and towns.
