Syrian troops crossed into Lebanese territory and clashed with opposition forces there, according to eye witness reports. Other sources say there was no actual incursion.
Some 35 Syrian soldiers riding in armored personnel vehicles and armed with machine guns and rocket propelled grenade launchers took part in the clashes, says Reuters, citing local residents.
The cross border attack, which left several farm buildings destroyed, was carried out on opposition fighters who are taking refuge in northern Lebanon.
A conflicting report says the clashes in the Mashareaa al-Qaa area did not involve an incursion. AP cites local police officials saying that the Syrian troops remained on their side of the border, but some bullets crossed into Lebanese territory.
Lebanon is located between the southern part of Syria and the Mediterranean Sea. According to the Syrian government, its poorly secured border with Lebanon has been a focal point for opposition forces smuggling weapons into the country.
