A series of Israeli strikes have targeted Beirut’s southern suburbs on the eve of the Muslim Eid al-Adha holiday, almost an hour after the Israeli army issued a forced evacuation order to residents in areas that it says held underground facilities used by the Lebanese group Hezbollah for drone production.

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.

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.
