Four people were killed on Saturday in Israeli strikes on southern Lebanon, Lebanon's state news agency reported, while the Israeli military said Hezbollah had fired ​rockets at Israel, posing the latest challenges to the tenuous ceasefire.

The ceasefire ​agreed between Israel and Lebanon has led to a significant ⁠reduction in hostilities, but Israel and militant group Hezbollah have continued to ​clash in southern Lebanon, where Israel has kept soldiers in the self-declared buffer ​zone.

A statement from Israeli Prime Minister Benjamin Netanyahu's office said the military had been instructed to attack Hezbollah targets in Lebanon forcefully, providing no further details.

The Israeli military said on ​Saturday that it had struck loaded rocket launchers belonging to Hezbollah in ​three locations in southern Lebanon overnight and targeted several Hezbollah fighters in separate strikes. It ‌said later ⁠in the day that it had also struck facilities used by Hezbollah's elite Radwan forces in southern Lebanon.

A Hezbollah lawmaker said on Friday that a US-mediated ceasefire in ⁠the conflict with Israel was meaningless, a day after ​it was extended for three weeks. The truce had been due to expire on Sunday.
