President Donald Trump and his national security team have talked about possibly restarting large-scale U.S. military operations in Iran in the coming weeks, NBC News reported, citing sources. That also includes the option of strikes prior to next month's midterm elections.

Meanwhile, tensions in the Middle East have been rising with Iran-backed Houthis recently targeting airports in Saudi Arabia, while Tehran has also been attacking tankers in the Hormuz Strait.
