Russian diplomats say two Russian citizens and an Italian have been kidnapped in Syria.
The Russian Embassy in Syria confirmed that the three, who work for a private company in Syria, were abducted along the Tartus-Homs highway.
Russia has a naval base in the western port town of Tartus.
Speaking to journalists in Tashkent, Russian Foreign Minister Sergey Lavrov said on December 18 that "all necessary steps are being taken in Syria and other countries that may influence the situation" to secure their release.
The Italian Foreign Ministry also confirmed the reports that an Italian national had been abducted.
No group has so far claimed responsibility, and no demands have been received.
