Israeli naval forces captured a senior Hezbollah operative in north Lebanon, an Israeli military official said Saturday, as the conflict between the Iran-backed group and Israel showed few signs of easing. Earlier on Saturday, Lebanese authorities said it was investigating whether Israel was behind the capture of a Lebanese sea captain who was taken away by a group of armed men who had landed on the coast near the northern town of Batroun on Friday. “The operative has been transferred to Israeli territory and is currently being investigated,” the military official said, without providing the name of the person in detention.
