Cristiano Ronaldo scored as Al-Nassr won an AFC Champions League match which was delayed by an hour because of a missile alert.

Ronaldo scored Al-Nassr’s second goal as the Saudi Pro League champions beat Uzbekistan’s Neftchi Fergana 3-1 on Monday.

Kick-off was delayed after Saudi Arabia’s Civil Defence issued a safety warning just 15 minutes before the scheduled start time in Riyadh, the capital city which has been the target of missiles fired from Yemen-based Houthis.

Following attacks on Riyadh’s airport, explosions were heard in the capital on Monday night. The Saudi-led military coalition said a ballistic missile had been intercepted and destroyed.

Future sporting events could be affected by the regional conflict, including Formula 1 races in Qatar and Abu Dhabi.

Once Al-Nassr were able to get under way, Ange Postecoglou’s team went ahead through Angelo in the 33rd minute and Ronaldo doubled their lead before half-time.

Uzbekistan champions Neftchi pulled a goal back, but they were reduced to 10 men after 65 minutes and an own goal 13 minutes later sealed a first Group B victory for the hosts.

Ronaldo also scored on Friday when making his return to club football, having left the Portugal national team camp halfway through the Nations League break out of frustration at limited playing opportunities.
