Rocket sirens sound in Upper Galilee and Nazareth

Up to 30 alerts were sounded in northern Israel in the areas of Nazareth and Upper Galilee on Saturday evening, according to an alert service monitoring rocket fire in Israel and Palestine.

It was not immediately clear what set off the alarms.

The Israeli army said no rockets were fired from Lebanon. It added the sirens were activated after an army drone malfunctioned and subsequently by a combat helicopter.
