Three paramedics affiliated with Hezbollah were killed in an Israeli strike on south Lebanon Monday, the group said, later announcing retaliatory fire, amid escalating cross-border hostilities during the Israel-Hamas war.
Israel and Hezbollah have been exchanging near-daily fire since the day after the Israel-Hamas war erupted in October, raising fears all-out conflict could spread across the region.
The Hezbollah-affiliated Islamic Health Committee said three volunteer paramedics died "due to a direct Zionist attack on an emergency centre" in south Lebanon's Odaisseh.
Hezbollah later said its fighters targeted Gesher Haziv near northern Israel's coastal city of Nahariya "with batches of Katyusha rockets" in retaliation, while the Israeli military said a number of launches were intercepted, reporting no wounded.
The deaths came hours after Israeli medics said a missile strike on northern Israel killed a foreign worker and wounded seven others, from India.
Hezbollah on Monday claimed several attacks on Israeli military positions, while the Israeli military said it struck Hezbollah targets including "military compounds" and a "command and control center" in southern Lebanon.
Lebanon's health ministry condemned the deadly Israeli raid in Odaisseh "in the strongest terms" and called attacks on medical personnel "unacceptable", in a statement carried by the state-run National News Agency.
