Donald Trump's appearance at the NATO summit in Turkey this week has triggered fresh health speculation, after close-up images of the US president's hand, showing visible bruising partially covered with makeup, circulated widely online during the two-day gathering.
The images, captured as Trump arrived and met world leaders at the NATO event, quickly drew scrutiny on social media, where users questioned both the cause of the discolouration and the apparent attempt to conceal it with concealer. The White House has maintained that the marks are benign.
