Australia is urging its citizens to ‘exercise a high degree of caution’ when visiting the UK following riots in multiple cities in recent days.

In an update to its travel advice, it said: “Avoid areas where protests are occurring due to the potential for disruption and violence.”

It told citizens they should monitor the media for information and updates.

Nigeria, Malaysia and Indonesia have also issued warnings for their citizens living in the UK, advising them to avoid crowds and remain vigilant.

The warnings follow days of riots in cities from Weymouth in the south to Sunderland in the north, and including – among others – Tamworth, Rotherham, Leeds, Manchester and Belfast.

The violent protests were sparked by the murders in Southport of three girls, including six-year-old Bebe King, whose mum works in the travel industry.

On Saturday night, a Hays Travel branch in Sunderland was vandalised during riots in the city.

So far, 378  people have been arrested since the disorder broke out last week. The National Police Chiefs’ Council Chairman Gavin Stephens said: “Every community across the country will have been affected in some way by the violent disorder we have seen in this past week.

“I want to reassure the public a united and robust policing response is in place across the country and we are doing all we can to tackle this disorder and keep you safe. 

“All forces have been requested not only to increase the number of specialist resources in their local area, but to contribute to regional reserves, coordinated nationally. 

“So far 378 arrests have been made and we expect that total to rise each day as forces continue to identify those involved and continue to apprehend those responsible. 

“Work is going on around the clock to do this and those involved will be brought to justice.”
