Tuesday's international friendly between Spain and Belgium in Brussels has been called off amid security concerns.
A Belgium national has been identified as the mastermind behind Friday night's terrorist attacks in France, when 129 people died.
Belgium's terror threat level was raised to three on Monday, which indicates a serious threat.
"Taking into account the exceptional circumstances, we cannot take any security risk to our players and fans," the Belgian FA said.
It also said that it "understands the disappointment of many supporters" and "deeply regretted" the late decision to cancel the match.
