Israeli warplanes struck two Hezbollah military buildings in southern Lebanon on Thursday, the military said.
A military statement said gunmen had holed up in the two buildings in the border town of Markaba.
The Israeli army also reported airstrikes on Hezbollah infrastructure in the occupied Shebaa Farms in southern Lebanon.
No reports were yet available about casualties or damage.
There was no comment from Hezbollah on the report.
Tensions have escalated along Lebanon's border with Israel amid an exchange of cross-border attacks between Hezbollah and Israeli forces as Tel Aviv pressed ahead with its deadly offensive on the Gaza Strip, which has killed nearly 34,600 people since last October following an attack by the Palestinian group Hamas.
