Lionel Messi posts cryptic one-word message after Argentina have goal disallowed an hour later in Olympics chaos
Argentina's last-gasp equaliser against Morocco was ruled out by VAR over an hour after Cristian Medina put the ball in the net.
In a match that started at 3pm and officially finished at 7:07pm local time, Morocco claimed victory over the World Cup winners in shocking circumstances.
Medina thought he had drew Argentina level when he headed in a equaliser in the 16th minute of extra time following a chaotic phase of play that saw the ball hit the post twice.
Almost immediately after there was trouble from the fans as bottles and cans were thrown at the celebrating players with some supporters also breaking onto the pitch.
Armed police were called to the pitch to calm the situation down.
Both sets of players were taken off the pitch with the match suspended with still seconds left on the clock.

A decision was then made that the rest of the match would be played in an empty stadium with the referee saying there was still three minutes to play.
All the fans inside the stadium at the Stade Geoffroy-Guichard in Saint-Etienne were forced to leave with police taking action.
And in what is the longest VAR check in history, Argentina's equaliser was ruled out after one of the players involved in the attack was offside when Medina scored.
VAR pictures showed that the Argentine was offside by the slimmest of margins with semi-automated technology making the decision.
The decision was cheered on the Morocco players, who had been forced to stick around.
Morocco went on to win the match 2-1 in the first men's football game of the Paris Olympics with the players having to undergo hefty warm-ups to get up to speed again.
