Iran failed to launch a satellite-carrying rocket in recent days, photos showed according to Associated Press.
The unsuccessful operation came as Tehran faces last-minute negotiations with world powers to save its nuclear deal in Vienna.
Satellite images from Maxar Technologies seen by The Associated Press show scorch marks at a launch pad at Imam Khomeini Spaceport in Iran's rural Semnan province on Sunday. A rocket stand on the pad appears scorched and damaged, with vehicles surrounding it. An object, possibly part of the gantry, sits near it.
Iran usually announces launches that reach space on its state-run television channels, but it has a history of not acknowledging failed attempts.
Separate images from Planet Labs PBC suggest the attempted launch likely occurred sometime after Friday.
Iran's mission to the United Nations did not immediately respond to a request for comment, nor did the U.S. military, AP said.
