Naharnet is quoting the UN as saying that the tree was on the Israeli side of the Blue Line.
It would appear that the LAF acted in error.
Quoted from the linked article:
UNIFIL military spokesperson Lt. Col. Naresh Bhatt said Wednesday that the tree that was the core of a deadly gunbattle between the Israeli and Lebanese armies is located inside Israeli territory.
Bhatt said investigations were still ongoing into Tuesday's border clashes.

He said Israel confirmed to the U.N. Secretary-General that notwithstanding their reservations identifying the line was solely the responsibility of the U.N. and that both Lebanon and Israel will respect the line as identified.
"The U.N. position is that the Blue Line must be respected in its entirety by all parties," Bhatt stressed.
Investigations are ongoing.
Let’s hope that calm prevails.
