Israeli media: Investigating posters found today in Tel Aviv, suspected to be related to a hacking group linked to Iran.
The announcement reads: "On that day, no power plant, refinery or desalination plant will remain standing in the occupied territories. From south to north, your energy and water arteries will shatter like glass. ".
"This is the last warning. The choice is yours: wisdom, or drowning in the darkness and silence of catastrophe. ".
