Silverstone has confirmed that the circuit is on "high alert" for threats of terrorism at this weekend's British Grand Prix.
The race comes just a week after 38 people, mostly British nationals, were shot dead on a beach in Tunisia, and two days before the 10th anniversary of the 7/7 suicide bomb attacks in London.
"Because it is a major, high-level sporting event, we were already on high alert. The level of the threat in the UK is 'severe' and it has not changed," The Mirror quotes a spokesperson for the track as saying.
"We have had a risk assessment by Northamptonshire police and security is based on that assessment."
A record 350,000 fans are expected to attend over the weekend, with 140,000 forecast for the race on Sunday.
