ROME, April 8 (Reuters) - Italy summoned the Israeli ambassador on Wednesday to demand an explanation over shots fired at an Italian convoy in a U.N. mission in Lebanon, the foreign minister said, warning Israeli forces had "no authority to touch" Rome's troops.
The U.N. peacekeeping force, known as UNIFIL, is stationed in southern Lebanon to monitor hostilities along a demarcation line with Israel - an area that has seen major clashes between Israeli troops and Iran-backed Hezbollah fighters.
