Recent reports indicate that sirens were activated in northern Israel as Hezbollah launched dozens of missiles into the region. Hezbollah announced it targeted Israeli forces operating within Lebanese territory on Sunday, amidst ongoing military incursions in southern Lebanon.

In a statement, the Israel War Room confirmed the activation of sirens, highlighting the escalating situation. Early Sunday, the Israeli military intercepted five projectiles fired from Lebanon, marking an intensifying exchange of fire. Over the weekend of Yom Kippur, the holiest day in the Jewish calendar, Hezbollah reportedly launched approximately 320 projectiles into Israel.

Simultaneously, Israeli forces targeted around 280 "terror targets" in Lebanon and Gaza during this period. In response to the escalating violence, Israel warned residents in southern Lebanon not to return home and issued evacuation alerts for several villages. UN peacekeepers in Lebanon have expressed concern about the potential for a "catastrophic" regional conflict.

Israel expanded its aerial bombardment of targets in Lebanon, hitting areas both in and outside traditional Hezbollah bastions, as its troops battled militants across the border on Sunday.

In areas where Hezbollah holds sway, Israeli warplanes hit a marketplace in the southern city of Nabatiyeh on Saturday, and then a 100-year-old mosque in a village near the border on Sunday, according to Lebanon's official National News Agency (NNA).

There have also been deadly strikes in other areas of Lebanon -- one on a Shiite Muslim village in a mostly Christian mountain area, and another in north Lebanon, the health ministry said.

The mayor of Kfar Tibnit, where the NNA said a strike destroyed a mosque, said he felt he had lost a beloved site that brought people together.

"It was a significant place because families used to gather in the square right next to it on special occasions," Fuad Yassin told AFP, adding that the mosque was at least 100 years old.

Lebanon's health ministry said strikes on three villages on Saturday killed 15 people. The Lebanese Red Cross said paramedics were lightly injured and ambulances destroyed in Sirbin when a house was hit by a second air strike as they searched for casualties.

Israel has alleged that militants use civilian infrastructure in Lebanon and Gaza to conduct operations -- a claim the groups have denied. The Israeli military said its 36th division continued "targeted and limited operational activity" in southern Lebanon against Hezbollah.

It said Israeli jets had hit "Hezbollah launchers, anti-tank missile posts, weapons storage facilities, and additional terror targets".On the ground, soldiers had "eliminated dozens of terrorists".
