Two major fires erupted in Iran on February 6, 2026, just after indirect U.S.–Iran nuclear talks in Oman, heightening regional tensions. A blaze hit a base linked to the Iranian Army’s Joint Staff in Tehran, which authorities blamed on an electrical fault, saying no casualties were reported. Hours earlier, another fire engulfed a factory in Ardabil city, sending thick smoke into the sky. The incidents followed Donald Trump’s warning of “steep consequences” if Iran rejects a deal and his claim that a U.S. armada is heading to the Middle East, fueling speculation.
