At least 274 people were killed and many more wounded in widespread Israeli airstrikes against Hezbollah targets in Lebanon, the country’s health ministry said on Monday.

Lebanese media reported that Israel sent text messages and took over radio stations in the country to urge civilians to flee areas where Hezbollah fighters were deployed, as well as sites used by the terror organization to store weapons and munitions.

Reuters reported that the IDF made more than 80,000 phone calls to residents to prevent civilian casualties.

The head of the United Nations Interim Force in Lebanon (UNIFIL) ordered all civilian members of the organization to leave areas south of the Litani River, according to the Lebanese Al-Akhbar news.

UN Resolution 1701, which ended the fighting during the Israel-Hezbollah war in 2006, stipulated that no Hezbollah force was allowed to enter areas south of the Litani. Since then, however, the Iranian-backed terrorist organization has developed its military infrastructure up to the Israeli border and deployed massive forces, with which it began its attacks on Israel on October 8, the day after the Hamas-led massacre in southern Israel.
