Libya's east-based army on Friday released two Libyan journalists arrested three weeks ago in the capital Tripoli.

Al-Sed Al-Garaj, father of one of the two journalists, told Xinhua that they were in good health and arrived in Zintan city, some 180 km southwest of Tripoli.

The two journalists, identified as Mohamed al-Garaj and Mohamed al-Shibani who work for the TV channel Libya al-Ahrar based in Turkey, were freed following tribal mediation, said a military source on condition of anonymity.

They disappeared on May 3 in southern Tripoli when covering the war between the army and the UN-backed government forces, hours before sources confirmed that they were in the custody of a brigade of the army in Tarhuna city, some 80 km south of Tripoli.

The army, led by Khalifa Haftar, has been leading a military campaign since early April to take over the capital from the government.

According to the World Health Organization, the fighting has so far killed 510 and injured 2,467 others.
