BEIRUT - Syrian air force warplanes bombarded rebel-held targets close to a major chemical weapons facility on Friday in fighting that highlights the perils facing an international mission to eliminate President Bashar Assad's chemical arsenal.
The Organization for the Prohibition of Chemical Weapons (OPCW), which was awarded the Nobel Peace Prize on Friday, is due to visit 20 sites across Syria to verify the destruction of 1,000 tonnes of chemical agents and precursors.
The mission in the midst of a civil war that has killed more than 100,000 people is an unprecedented challenge for the OPCW, whose members came under fire near Damascus in August.
The OPCW experts have visited three undisclosed sites in their first week of operation and say that Syrian authorities have been cooperating. But they will face great challenges reaching locations in rebel-held or disputed territory.
The air raids struck the town of Safira, on the edge of a sprawling military complex believed to hold chemical weapons production facilities, after overnight clashes between rebel fighters and Assad forces in a nearby village, activists said.
