The International Tennis Federation has expressed its concerns over security just six days before the Davis Cup final.
Great Britain will compete with Belgium in Ghent next weekend amid heightened tensions following recent terror attacks and the discovery of a cell in Brussels, 35 miles away.
ITF president David Haggerty told the BBC there had been “constant contact with the relevant authorities, adding: “We are aware that Belgium has raised the terror alert level for Brussels. This greatly concerns us but, at the present time, we are still continuing with preparations.”
A number of sports events were postponed in the country this weekend and the British Foreign Office has warned anyone travelling to Belgium to avoid crowded areas where possible.
Its website read: “People should avoid places where there is a high concentration of people, particularly in the Brussels region, including concerts, large events, stations and airports, public transport, and busy shopping centres.”
Great Britain captain Leon Smith is understood to have asked the players for their opinions on the match but they remain ready to travel and play as planned.
It will be played at the 13,000 capacity Flanders Expo from Friday, 27 November to Sunday, 29 November.
A Davis Cup ties last September between Ukraine and Belgium was moved to Tallinn, in Estonia, because of the conflict in eastern Ukraine. Israel’s tie with Argentina, which was played the same week, was moved from Tel Aviv to Florida due to concerns arising from the conflict between Israel and Hamas.
