Iran shut down the Strait of Hormuz for a few hours on Tuesday, Iranian state media reported, without making clear whether the waterway, one of the world's most vital oil export routes, had fully reopened.

The day before nuclear talks were set to resume, Iran conducted live drills in the Strait of Hormuz, a strategic waterway for oil and gas shipments.
