At least seven people were killed in an Israeli strike on Nabatieh in southern Lebanon, drawing retaliatory Hezbollah rocket fire on Wednesday.
The strike targeted the Islamic Group's emergency and relief center in Hebbariyeh village.
Hezbollah said on Wednesday it launched dozens of rockets at Kiryet Shmona, a northern Israeli town close to the Lebanese border, in response to deadly Israeli strikes on south Lebanon on Tuesday.
Israeli emergency services said a rocket strike killed a factory worker in Kiryat Shmona following warning signs in the area.
Paramedics from the MDA ambulance service said the man was pulled from the wreckage of the factory with severe wounds and was pronounced dead at the scene.
On Tuesday, Israeli airstrikes near two towns in northeast Lebanon killed three Hezbollah members, the group posted on Telegram.
Israel confirmed the strikes near Ras Baalbek and Hermel and said its aircraft targeted a number of military sites used by Hezbollah in response to a rocket attack on one of its bases near the Lebanese border.
Hezbollah and the Israeli army have been trading fire since October in the worst cross-border violence since they fought a month-long war in 2006.
