The Israeli military has instructed residents in dozens of northern communities to stay near shelters and avoid non-essential outdoor activities due to possible “retaliation” from Hezbollah.

Thousands of pagers and handheld radios used by Hezbollah members exploded across Lebanon on Tuesday and Wednesday. Lebanese Health Minister Firas Abiad said the blasts resulted in at least 37 fatalities and 2,931 injuries. Although Israel has not claimed responsibility for the explosions, Hezbollah has attributed the incidents to Israel and vowed to retaliate.

Residents in the Upper Galilee and the occupied Golan Heights were on Thursday night requested to minimize movement, avoid gatherings, monitor gates at the entrances to communities, and remain close to shelters.
