U.S. President Donald Trump on Friday posted on Twitter a photo of what appeared to be the site of a failed Iranian satellite launch, raising questions about whether he had disclosed U.S. surveillance secrets.

The black-and-white photo showed the fire-blasted launch site at a space center in northern Iran, including a damaged gantry service tower and a downed mobile erector launcher.

Trump, in his tweet, cited the specific location of the site, saying the United States was not involved in the "catastrophic accident during final launch preparations for the Safir SLV Launch at Semnan Launch Site One in Iran."
