(Reuters) - The second half of Wednesday's Copa America semi-final between Chile and Colombia in Chicago has restarted after a delay of more than two hours due to torrential rain.

The teams kicked off again at Soldier Field with Chile leading 2-0.

Thousands of fans had huddled in stadium corridors or under cover while the worst of the rain passed. The game was restarted after officials did their best to sweep puddles of water off the pitch.

The winner of Wednesday's match goes on to face Argentina in the final.
