BEIRUT - Israeli forces launched strikes on Lebanon including the capital Beirut on Monday, the military said, after Tehran-backed militant group Hezbollah fired rockets at Israel in retaliation for the killing of Iran's supreme leader.
An AFP journalist heard several loud explosions in Beirut early on Monday, the Israeli military said it had "begun striking targets of the Hezbollah terrorist organisation across Lebanon".
Residents in southern Lebanon fled on cars, some with mattresses tied to the roof, an AFP journalist saw, after Israel issued a mass evacuation warning.
The Israeli strikes followed rocket and drone launches from Lebanon, the first attack on Israel claimed by Hezbollah since a November 2024 ceasefire agreement that followed more than a year of war between them.
Hezbollah has been weakened from conflict with Israel, which it entered to support Hamas following the Palestinian militant group's deadly attack on Israel in October 2023 and the subsequent war in the Gaza strip.
Israel has carried out regular strikes on Lebanon since the ceasefire came into effect, usually saying it targets the militant group and accusing it of truce violations.
On Monday, a military statement said Israeli forces "precisely struck" senior Hezbollah members in the Beirut area, and another in the south.
Lebanon's state-run National News Agency (NNA) reported Israeli strikes across the country, including in Beirut's southern suburbs where Hezbollah holds sway.
Israel then issued a warning to residents of about 50 towns and villages in Lebanon's south and east -- both Hezbollah strongholds.
"Hezbollah's actions force the IDF (army) to act against it... For your safety, evacuate your homes immediately and move at least 1,000 metres (0.6 miles) away from your village to open areas," army spokeswoman Ella Waweya said in a statement on X.
Hezbollah earlier claimed responsibility for the rocket and drone attack on Israel, which it said was retaliation for the killing of Iranian supreme leader Ayatollah Ali Khamenei in a wave of US-Israeli strikes on Tehran at the weekend.
It was also "in defence of Lebanon and its people, and in response to the repeated Israeli attacks", Hezbollah said.
An official from the group had told AFP last week that Hezbollah would not intervene militarily in the event of "limited" US strikes on its backer Iran, but would consider any attack against Khamenei a "red line".
