Israel’s military said it was targeting an underground drone facility in southern Beirut on Thursday, in one of its largest strikes on Hezbollah assets since a cease-fire was agreed to in November. The military said Hezbollah’s aerial unit was producing thousands of drones with help and funding frin Iran.

A series of Israeli strikes have targeted Beirut’s southern suburbs, almost an hour after the Israeli army issued an evacuation order to residents of the area, in areas that it said held underground facilities used by Lebanese group Hezbollah for drone production.

Israel warned Friday that it will keep striking Lebanon until militant group Hezbollah has been disarmed, hours after it hit south Beirut in what Lebanese leaders called a major violation of a November ceasefire.
