Pope funeral: Trump and Zelensky observe service

Pope Francis's funeral saw leaders from around the world turn out to pay their last respects in Vatican City. As with many funerals, there was a sombre dress code of black suit, black tie and white shirt for men while women were advised to dress in long, black dresses with gloves and a veil.

But a few leaders didn't follow the code, including US President Donald Trump and his Ukrainian counterpart Volodymyr Zelensky, who wore a black jacket, black shirt and trousers, but no tie. It's well-known that Mr Zelensky dresses in a style reminiscent of a military uniform to remind the world his country is at war.
