The Philippine Embassy in Tripoli got in touch with one of the nurses, who said they were all safe, Department of Foreign Affairs spokesman Charles Jose said.
An official of a militia battling the Islamic State group affiliate had reported the kidnappings in the Libyan city of Sirte yesterday.
Jose, however, said "a local friend who was concerned for their safety" had actually taken the nurses from their accommodation to a "safer place."
An official from the 166 Battalion, which is battling the Islamic State group affiliate, had said the kidnappings took place yesterday afternoon at Sirte's main hospital, Ibn Sina. He said his battalion helped evacuate the remaining foreign medical crew in the hospital to the Libyan city of Misrata, where the battalion is based.
The Philippines, one of the world's largest labor exporters, has banned the deployment of workers to Libya due to the escalating violence in the country. About 4,000 Filipino workers and dependents have remained in Libya despite a government offer to repatriate them, Jose said.
