It has been revealed that the US first lady is reportedly trapped inside her hotel in Hamburg as a result of anti-capitalist protesters surrounding the building.

A US delegation spokesperson told German media that they had been unable to get clearance for Ms Trump to leave the hotel where she is staying.

Nevertheless, Mrs. Trump has expressed her sympathies for those hurt in the protests which erupted across Germany's second largest city and urged people to remain safe on Twitter.

Thinking of those hurt in #Hamburg protests. Hope everyone stay safe! #G20

President Trump, however, made it to the summit on time after driving through the city at a fast speed under heavy police escort.

Joachim Sauer,the German Chancellor’s husband, was due to take Ms Trump on a tour of the German Climate Computing Centre with the US President's daughter, Ivanka Trump, and other spouses of G20 leaders on Friday.

German officials said the idea for the visit came from Mr Sauer who is a professor of physical and theoretical chemistry.

The centre, which uses super-computers to map climate change’s effect on regions across the world, is situated near the secured hall where Ms Merkel, President Trump, and other leaders are meeting.

Other partners, including Ms May's husband Philip, Emmanuel Macron's wife Brigitte Macron, and Canadian Prime Minister Justin Trudeau's wife Sophie Gregoire Trudeau are currently on the sightseeing tour with Mr Sauer which also involves a boat ride and lunch.

The Australian prime minister, Malcolm Turnbull, tweeted that he was under “security lockdown” with the Indonesian president, Joko Widodo. Police protecting the hotel where Mr Turnbull is staying briefly came face to face with protesters at one point.

At least 76 people were hurt in clashes with police in Hamburg as the force used water cannons on black-clad protesters who threw water bottles.

The "Welcome to Hell" rally is one of a number of protests held in the city against both the G20 summit and Mr Trump's maiden appearance there.
