ARSAL, Lebanon, Dec. 30 (UPI) -- Lebanese troops fired at Syrian warplanes for what is believed the first time since the start of the Syrian conflict, Lebanon's news agency reported Monday.
The Syrian military planes were violating Lebanese air space over the village of Arsal, near the Syria-Lebanon border, 124 kilometers (77 miles) northeast of Beirut, Lebanon's National News Agency reported.
There were no reports of casualties.
Lebanese authorities did not respond to previous actions by the Syrian military in which shots have been fired over the border at rebels, to keep from being drawn into the war in Syria, the British Broadcasting Corp. reported.
Arsal has been overwhelmed with about 20,000 refugees since the Syrian military launched an offensive in the nearby Qalamoun mountains last month, the BBC added.
