Donald Trump on Thursday said the U.S. would hit Iran “VERY HARD TONIGHT,” threatening in a social media post to “assume total control” of Iran’s oil and gas industries, including the key Kharg Island, in the “not too distant future.”

The post come after the U.S and Iran traded strikes for a second day, pushing the Middle East closer to the resumption of a full-scale war. The American attack, which lasted into Thursday morning in Iran, appeared more intense and wider than the day before.
