Lebanese media reports heavy Israeli artillery shelling toward the border village of Wazzani, close to Ghajar.
The reports come amid growing indications of an imminent Israeli ground incursion into southern Lebanon.
I couldn’t find many details yet online on any news sites. There are some video clips on various sites, not much commentary.
EDIT: This says that tank fire is involved, not whether it’s direct or being used as short range artillery, though:

Ground operation in Lebanon begins with heavy artillery, tank fire
On the Saudi Al-Hadath network a report said that there is “Israeli preparation for the entry of ground forces and commando forces, in order to locate Hezbollah targets and blow them up.” Another Saudi network, Al-Arabiya reported that tanks penetrated Rmaich in southern Lebanon, but later deleted that report.
So maybe not direct engagement on the ground yet, but I assume that that’s imminent.
