Lebanon filed a complaint on Thursday against Israel at the UN Security Council, saying it had violated its sovereignty by opening fire on its territory in retaliation for rocket attacks.
The foreign ministry said Israel fired 102 shells at Lebanon between July 11 and 14, during the ongoing war between Israel and Gaza, describing this as "repeated and dangerous violations".
During that same period at least nine rockets were fired from south Lebanon into Israel.
Israel has responded with artillery fire.
The foreign ministry said Lebanon "rejects the firing of rockets (from its territory) on occupied Palestinian territory," in a reference to Israel.
This action "is a threat to peace and stability that serves neither Lebanon nor the Palestinian resistance, and gives Israel reason to attack Lebanon and its sovereignty," it added.
On Wednesday the Lebanese army announced that two Palestinian brothers suspected of involvement in rocket attacks on northern Israel had been arrested.
