JAKARTA (REUTERS) - The Indonesia Football Association (PSSI) has been fined US$15,000 (S$18,835) for repeated crowd infringements at international matches, the Asian Football Confederation announced on Monday.

The PSSI was fined US$10,000 after fans ignited firecrackers and threw water bottles during Indonesia's March 23 Asian Cup home qualifier against Saudi Arabia, with the additional US$5,000 a result of similar incidents during four matches last year.

Indonesia will also have to play a match behind closed doors if the problem recurs in the next two years, the AFC said.

The AFC also handed a US$5,000 fine to Brunei, who pulled out of the AFC Challenge Cup at the last moment citing "unavoidable circumstances".
