Chile have been forced to temporarily suspend a World Cup practice session because of a Brazilian news helicopter flying over the team's base.

Jorge Sampaoli's outfit, who qualified from Group B thanks to wins over Spain and Australia, were training at the Toca da Raposa II facility in Belo Horizonte when a helicopter from news network Globo was spotted overhead.

According to The AP, the team's communications director, Hector Olave, asked the network not to broadcast any of the images so Chile's tactics wouldn't be revealed.

"We tried to hit [the helicopter] with the ball, but we couldn't," Chile defender Mauricio Isla told reporters.

The two countries will meet in the second round of the World Cup in Belo Horizonte this Saturday.
