The deployment took place on Thursday along the barb-wired fence which separates the Shebaa Farms from other parts of Lebanese territories.
Israeli tanks were also gathering along a 5-km area, stretching from the Tallat Sobaih army post to Mount Hermon while sporadic gunfire was also heard throughout the day, the agency reported.
The Israeli air force also carried out a number of flights over the Shebaa Farms, al-Arqoub villages, Hasbaya, Marjayoun, western Bekaa and Iqlim al-Tuffah.
Shebaa Farms comprises of a group of 14 farms close to the poorly-defined border of Lebanon and Syria. The farms were captured from Syria during the Six-Day Israeli War in 1967.
Lebanon says that Israel must leave the Shebaa Farms area, which it says lies on Lebanese territory while Israel contests this claim. Israel says that Shebaa is part of Syria's territory and its fate should be discussed in future peace talks with Damascus.
