Bosnia-Herzegovina and Poland have been fined by FIFA and warned over the future conduct of their fans after crowd disturbances in March.
FIFA's disciplinary committee decreed that the Football Federation of Bosnia-Herzegovina must pay 50,000 Swiss Francs (33,300 euros) after fireworks were set off by away fans in the game against Belgium in Genk on March 29.
The incident led to an eight-minute delay when the players were evacuated from the pitch and a supporter also invaded the playing area.
The Polish Football Association were fined 25,000 Swiss Francs (16,650 euros) following their World Cup qualifier in Northern Ireland the day before.
Polish fans were also found to have released fireworks, while police had objects thrown at them in the away end.
The disciplinary committee met in Zurich on May 7 and, in addition to the fines, warned both associations as to their future conduct.
A statement added: "Should incidents of such gravity occur again, harsher sanctions, such as a points deduction or elimination of the representative team from a respective tournament, will be imposed by the FIFA disciplinary committee."
An additional fine of 25,000 Swiss Frances (16,650 euros) was also handed to the Greek Football Federation in relation to the use of lasers and display of politically-motivated banners during Greece's home clash with Israel on April 1.
