Israel's strikes on 30 Iranian fuel depots Saturday went far beyond what the U.S. expected when Israel notified it in advance, sparking the first significant disagreement between the allies since the war began eight days ago, according to a U.S. official, Israeli official and a source with knowledge. Why it matters: The U.S. is concerned Israeli strikes on infrastructure that serves ordinary Iranians could backfire strategically, rallying Iranian society to support the regime and driving up oil prices. Driving the news: The Israeli air force's Saturday strikes created large fires in Tehran, igniting flames visible for miles and blanketing the capital in heavy smoke. The IDF claimed in a statement that the fuel depots "are used by the Iranian regime to supply fuel to different consumers including its military organs."
