The International Tennis Federation (ITF) will heighten security at the forthcoming Davis Cup final in Ghent following Friday's terror attacks in Paris.
More than 1,000 fans are expected to travel to Belgium from Nov. 27-29 to support Andy Murray and his team in what will be Great Britain's first final since 1978.
Security concerns have been raised with the Brussels suburb of Molenbeek -- where Belgian police have made several arrests in relation to the investigations into the Paris attacks -- just 35 miles from the Flanders Expo Arena, the final venue.
ITF president David Haggerty was quoted by the Times: "Following the tragic events over the last few weeks all sporting events require heightened levels of security and this includes both the Fed Cup and Davis Cup finals.
"For our finals and other ITF events, we follow a rigorous process that includes regular consultation with our experts to ensure that we take every precaution to safeguard our events, fans and players."
Paris is only three hours' drive away from Ghent and, while there was no indication the final between Great Britain and Belgium would be postponed, security will now be raised to an unprecedented level. Airport, railway and border security have all been strengthened.
An ITF statement read: "At every ITF event we take security very seriously and Ghent will be no exception. We work very closely with the host association and also with our risk assessors to ensure the security of the teams, the spectators and everyone else who is working on site including media, ITF and national association staff and other workers."
In the wake of Friday's events, security has also been heightened at the ATP World Tour Finals in London, with bag checks increased at the O2 Arena.
