The US Embassy in London on Tuesday issued an alert warning Americans visiting or living in the UK to “keep a low profile” and take other measures to stay safe during President Trump’s visit to Great Britain.

“Numerous demonstrations are being planned for July 12 to 14, surrounding the visit of the President of the United States to the United Kingdom,” the alert on the embassy’s website reads.

“The majority of the demonstrations will be focused in central London on July 13, with other events planned for July 12 and 14. Several of the events are expected to attract large crowds and there will be road closures in connection with those events.”

The alert tells Americans to “be aware of your surroundings” and to “exercise caution if unexpectedly in the vicinity of large gatherings that may become violent.”

The warning continues: “Keep a low profile. Monitor local media for updates. View updates from UK police” on Twitter.

It also includes contact information for the embassy and the State Department.

Trump arrives in the UK for a visit beginning July 13, and widespread protests are expected — with at least one featuring a huge balloon depicting Trump as a baby in diapers clutching a cellphone.

Meanwhile, protesters are working to make Green Day‘s “American Idiot” the No. 1 song on the English charts in time for the commander-in-chief’s visit, which will largely bypass London.

As of Tuesday afternoon, the 2004 song was the No. 1 song on Amazon’s UK best-seller list, Entertainment Weekly reported.

It’s also at No. 18 on the country’s Official Singles Chart, and according to Chart Data, it was off and on the Top 10 and Top 20 lists.

A Facebook group backing the campaign has more than 20,000 followers, and has been calling on them to download “American Idiot” between July 6 and July 12.

Responding to questions about the stunt, the FB group said they thought making the song No. 1 would be funny.

“Because we’d find it hilarious and reckon thousands more will find it hilarious too. If you don’t like then great…just don’t like it then, but we really couldn’t care less. We’re doing this anyway,” they wrote.

Virginia Sen. Tim Kaine also cited the song on Twitter after it was revealed that Trump hoped to send an Elton John CD with the song “Rocket Man” to North Korean dictator Kim Jong Un, whom he famously dubbed “Little Rocket Man.”

“And Kim Jong Un sends back a copy of Green Day’s ‘American Idiot,’” Kaine wrote on Twitter on July 6.
