Israel launched its most extensive series of airstrikes on the Dahiyeh suburb of Beirut on Thursday, as well as Ain Qana in south Lebanon, stating it targeted Hezbollah drone production and storage facilities.

The airstrikes on the southern outskirts of the Lebanese capital, an area where Hezbollah holds sway, were some of the heaviest since a U.S.-brokered cease-fire came into effect in November.

Israel has continued to carry out near-daily strikes in southern and eastern Lebanon since the ceasefire, which Lebanon has said are in violation of the agreement. Israeli officials say the strikes are intended to prevent Hezbollah from regrouping after a war that took out much of its senior leadership and arsenal.
