UNIFIL mission head Major-General Luciano Portolano called for "utmost restraint against any provocation," after Hezbollah launched explosives at IDF troops in northern Israel and Israel retaliated by shelling targets in Lebanon.

Hezbollah chief Hassan Nasrallah vowed last month to avenge the death of terrorist Samir Kantar, who was imprisoned in Israel for decades for the 1979 murder of three Israelis, AFP reports.
