Israeli shelling killed two people in south Lebanon on Friday, a Lebanese official said, as the collapse of a truce between Israel and the Palestinian militant group Hamas prompted a resumption of hostilities at the frontier.
The Iran-backed Lebanese group Hezbollah, a Hamas ally, said it had carried out several attacks on Israeli military positions at the border in support Palestinians in the Gaza Strip, where a weeklong pause in the fighting ended early on Friday.
The Israeli army said its artillery struck sources of fire from Lebanon and air defenses had intercepted two launches. The army also said it struck a "terrorist cell". Sirens warning of possible incoming rockets sounded in several towns in northern Israel, sending residents running for shelter.
Israeli shelling killed a woman and her 35-year-old son in the Lebanese border town of Houla, Shakeeb Koteich, the head of the town's municipal council, told Reuters, saying both were civilians.
"A shell landed near the house, and then a second one hit the house," Koteich said by telephone.
Following the eruption of the Hamas-Israel war on Oct. 7, Hezbollah mounted near daily rocket attacks on Israeli positions at the frontier while Israel waged air and artillery strikes in south Lebanon.
It has been the worst fighting since a 2006 war between Israel and Hezbollah, part of an Iran-backed alliance that also includes Hamas. About 100 people in Lebanon have been killed during the hostilities, 80 of them Hezbollah fighters. Tens of thousands of people have fled both sides of the border.
Hezbollah released statements claiming five attacks on Israeli military positions at the border, describing these as "in support of our steadfast Palestinian people ... and its valiant and honorable resistance".
Lebanon-based militants from Hamas and the Palestinian group Islamic Jihad have also mounted attacks from Lebanese territory.
"Hezbollah has linked what happens at the border with what happens in Gaza," said Nabil Boumonsef, deputy editor-in-chief of Lebanon's Annahar newspaper.
"All the while the war in Gaza continues Lebanon will remain threatened by the danger of a major escalation."
Senior Hezbollah politician Hassan Fadlallah earlier said the group was vigilant and ready after the Hamas-Israel truce ended.
"In Lebanon, we are concerned in facing this challenge, being vigilant, and always ready to confront any possibility and any danger that may arise in our country," he said.
"No one thinks that Lebanon has been spared from this Zionist targeting or that what is happening in Gaza cannot affect the situation in Lebanon," he said.
