Donald Trump, the U.S. president, said the United States is continuously monitoring activities related to Iran’s nuclear facilities and said Washington has accurate information about traffic around these sites.

In response to a question about nuclear materials that may still remain in Iran, Trump said: “They had three sites and now they may have the quarry mountain of Gizra. Those three sites are completely destroyed.”

He added: “We have cameras over all the main areas of those three sites, and we also have cameras over the quarry mountain of Gizra. We know who enters there and who leaves there.”

Trump then said America’s surveillance capabilities are so precise that one can even detect very fine details from space, including people’s names on their identification cards, and added that Washington has “high confidence” in what is happening in those areas.

He said that is why the U.S. administration has “a great deal of confidence” in its information about what is taking place in those areas.
