The Great Britain Davis Cup final team have delayed their departure to Belgium as Brussels remains on its highest level of terror alert.
Leon Smith's squad, which includes British No.1 Andy Murray, is now expected to travel on Monday for the tie in Ghent, a little more than 30 miles from the country's capital.
According to the BBC, Brussels has moved into a second day of a security lockdown, with Metro services suspended until Monday, and residents told to avoid crowded areas. The Belgian government will review the security situation in Brussels later on Sunday.
On Saturday, the International Tennis Federation said it is "greatly concerned" but insisted preparations for the final continue.
