Rescuers on May 20 found a helicopter that was carrying Iranian President Ebrahim Raisi, the country’s foreign minister and other officials that had apparently crashed in the mountainous northwest reaches of Iran the day before, though “no sign of life” was detected, state media reported.

Early on Monday morning, Turkish authorities released what they described as drone footage showing what appeared to be a fire in the wilderness that they “suspected to be wreckage of helicopter.”

The coordinates listed in the footage put the fire some 20 kilometers (12 miles) south of the Azerbaijan-Iranian border on the side of a steep mountain.
