Lebanon's official National News Agency reported that the strike was carried out by "an Israeli drone". Israel frequently launches strikes in Lebanon, saying it is targeting Hezbollah, despite a ceasefire that brought its most recent war with the group to a halt in November.
Baalbek, a millennia-old city and home to a set of UNESCO World Heritage-listed Roman temples, sits in the Bekaa Valley, which is close to the Syrian border and has been a stronghold for Hezbollah.
Under pressure from the United States and fearing an escalation of Israeli strikes, the Lebanese government is now moving to disarm Hezbollah.
The group, which previously dominated Lebanese politics and was thought to be better armed than the military, was severely weakened by the war with Israel.
According to Beirut, the Lebanese army must complete its disarmament of Hezbollah in areas near the Israeli border within three months.
