President Donald Trump is issuing a stark warning to Iran against retaliating against U.S. targets in the Middle East while also predicting Israel and Iran would “soon” make a deal to end their escalating conflict.

Separately in the city’s south, Shahr Rey, one of the country’s largest oil refineries, was also struck, according to Iranian state news media. Emergency crews were trying to contain the fire, and a resident of Tehran, Reza Salehi, said he could see the flames from miles away.
