Donald Trump provided a moment of light relief on his trip to Japan after social media users highlighted his unsubtle fish feeding technique.

The US president followed the lead of Japan Prime Minister Shinzo Abe as they fed koi fish at the Akasaka Palace in Tokyo.

They began by gently spooning some pellets for the fish, but finished the feeding frenzy abruptly by dumping the remaining contents of their boxes into the lake below.

Mr Trump unceremoniously turned his box upside down and appeared to make a sound effect as the food hit the water.

His Japanese host raised a smile after their encounter on the palace balcony, as Rex Tillerson and a woman dressed in a kimono watched on.
