The International Committee of the Red Cross says medical services in Libya's rebel controlled western mountains are struggling with a flood of casualties from fighting.
Tuesday's statement from the Red Cross said facilities lack medicines to treat patients and vaccines to deal with outbreaks of disease.
An ICRC delegation visited the region and provided bandages and other medical materials.
Arab and Berber rebels wrested control of much of the Nafusa mountains from the government weeks ago. The range stretches from the Tunisian border to within 60 miles (100 kilometers) of Tripoli.
But rebels have been unable to capture the strategic mountain town of Gharyan, which controls the approach to the capital.
