Dramatic photos have emerged of the rescue mission to save two stranded window cleaners who clung on to the 68th floor of One World Trade Center in New York for more than 90 minutes.

The men were left dangling perilously high when the platform they were on jackknifed approximately 400m off the ground at 12.45pm local time.

Neither of the stranded cleaners sustained any injuries during the malfunction and a specialist NYFD crew was able to pull the men to safety after cutting through layers of glass from the interior of the skyscraper to reach them.
