Crowd trouble forced the first football match of the Olympics to be delayed by more than an hour.

Morocco had been 2-0 ahead against Argentina, but Cristian Medina equalised in dramatic fashion with a header in the 16th of 15 scheduled minutes of injury time at the end of the second half.

A number of cups and bottles were then thrown at the celebrating Argentina side before what appeared to be a flare landed near the players and coaching staff.

A number of fans in Morocco colours also ran on to the pitch.

The referee immediately took the players off the pitch and a message on a big screen in the stadium said: “Your session has been suspended please make your way to the nearest exit.”

However, it was then reported the final three minutes remaining in the match would be played in an empty stadium with no fans present.
