The rockets which landed in the Wadi Khaled area in the Bekaa, damaged a number of resident houses, according to National News Agency (NNA).
There was no report of human casualty and the exact sources of the rocket attacks are not known.
The Syrian conflict has increasingly spilled over into Lebanon, and has raised tensions in the country.
In mid-June, at least one person died and several others sustained injuries in a rockets attack carried out by militants in Syria against neighboring Lebanon’s border town of Hermel.
The militants fighting to seize power in Syria fired 12 rockets into the northeastern Lebanese town of Hermel in Bekaa Valley on Tuesday.
The attack caused heavy damage to some residential buildings.
There has been an upsurge in such assaults after the Syrian army managed to inflict major losses on foreign-sponsored militants in the country, gaining a series of military victories in its fight against the armed groups.
Foreign-sponsored militancy in Syria, which erupted in March 2011, has claimed the lives of many people, including large numbers of Syrian soldiers and security personnel.
