Sources differed on whether the strike took place on Syrian or Lebanese territory.
"The Israeli air force blew up a convoy that had just crossed the border from Syria into Lebanon," one source said, adding that the convoy was believed to be carrying weapons, without specifying the type.
A Zionist Regime military spokeswoman declined to comment on the report.
A second security source, speaking on condition of anonymity due to the sensitivity of the issue, also confirmed to AFP that Israeli warplanes had hit a convoy allegedly carrying weapons to Lebanon but said the incident occurred just inside Syria.
"It was an armed convoy travelling towards Lebanon but it was hit on the Syrian side of the border at around 2330 GMT," the source said.
Both sources reported a high level of "unusual" Israeli activity over Lebanese air space, which began on Tuesday evening and continued overnight.
The Lebanese army confirmed that Zionist Regime’s warplanes entered Lebanese airspace up to 16 times between 9:30am (0730 GMT) Tuesday and 2:00am Wednesday.
