The US celebrates the 250th anniversary of its independence on Saturday, in what the White House has called "the most important milestone" in the nation's history.

Fireworks displays, air shows, and a speech from US President Donald Trump are all part of the planned festivities, which Washington hopes will help "inspire a renewed love for American history".

Governments, officials, and royals from across Europe have joined the US in celebrating the day.

Here are some of the messages they've sent.
