Iranian television published instructions for surviving a nuclear attack. Citizens were urged not to look at the explosion, take shelter in permanent structures, use only bottled water and stay away from windows. Iranians were advised to stay in shelters for at least 24 hours and not leave until emergency services said it was safe to do so. "Don't assume that after 24 hours the situation will be safe. Follow official announcements regarding safe evacuation routes," the warning said. Earlier, the journalist Tucker Carlson said that the Trump administration may launch a nuclear attack on Iran in the coming days under pressure from Netanyahu. According to sources, the United States has already concentrated enough forces in the Middle East to strike as soon as possible - perhaps as early as this week. Israel called the statements of an American journalist "delusional".
