War-torn neighbours Syria and Iraq continued their unbeaten starts to the Asian World Cup qualifying competition but crowd trouble forced an abandonement of Malaysia's qualifier against Saudi Arabia.
Saudi Arabia were leading 2-1 in the Group A Asian qualifier at Shah Alam Stadium in Selangor when play was stopped in the 87th minute after fans launched flares and fireworks onto the pitch.
Players from both teams left the field and did not return. The match was later abandoned with the outcome to be decided by the sport's world governing body FIFA.
Malaysia suffered a record 10-0 loss to United Arab Emirates last week, infuriating fans and prompting the resignation of head coach Dollah Salleh.

Malaysia's Youth and Sports Minister Khairy Jamaluddin later blamed the unruly fans and the Football Association of Malaysia (FAM), saying they had failed to control the situation.
"FAM lost control of their own stadium. Fans throwing flares were wrong. Both at fault tonight," Khairy said in a tweet.
The crowd problems overshadowed another remarkable win by Syria, who have never qualified for the World Cup but have defied the odds to lead a qualifying group that includes Japan.
Forced to play all their matches away because of the problems in their homeland, the Eagles made it three wins from three matches with a 6-0 thrashing of Cambodia at the Olympic Stadium in Phnom Penh.
