According to Lebanon’s official news agency, Israeli shelling in south Lebanon on Friday resulted in the deaths of three individuals as hostilities along the border resumed due to the breakdown of a truce between Israel and the Palestinian militant organization Hamas.

Hezbollah, an ally of Hamas and a Lebanese militia sponsored by Iran, later claimed that one of its members was among the dead. It said that it had supported Palestinians in Gaza, where a week-long ceasefire in hostilities collapsed early on Friday, by carrying out multiple attacks against Israeli military positions along the border.

The Israeli army said its artillery struck sources of fire from Lebanon and air defences 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.

Lebanon’s state news agency reported that two people were killed by Israeli shelling in the Lebanese border town of Houla, and one person was killed in the village of Jebbayn.

Israeli shelling killed a woman and her 35-year-old son in Houla, Shakeeb Koteich, the head of the town’s municipal council, told Reuters, saying both were civilians. Hezbollah later said a “martyr” was killed in Houla.

“A shell landed near the house, and then a second one hit the house,” Koteich said by telephone.
