An Israeli fighter jet launched an airstrike in southern Lebanon, said the Israel Defense Forces (IDF) in a statement, claiming the attack aimed to “thwart a threat.”

This is reportedly the first strike of its kind took place on Thursday since the ceasefire deal between Israel and Hezbollah in Lebanon took effect early Wednesday morning.

The IDF statement said that “terrorist activities were identified in a facility used by Hezbollah to store mid-range rockets in southern Lebanon,” adding, “The IDF troops are deployed in southern Lebanon, operating to prevent any violation of the ceasefire.”
