The British government says fans arriving in South Africa for next year's World Cup could be at risk of carjacking when they leave Johannesburg airport.
A new rail link from the airport has already been curtailed and may not be ready in time for the start of the monthlong tournament on June 11.
That will leave most fans hiring cars or taking taxis, and the government's foreign office says they should be on guard.
Foreign office minister Chris Bryant says "it is crucial that those planning to travel to the region are aware of what measures they should take to stay safe."
