“US and Mexican police have discovered a tunnel used to smuggle drugs across the California-Mexico border and seized some 25 tonnes of marijuana.

The tunnel, equipped with ventilation, lighting and a pulley system, was 550m (1,800ft) long but just waist high.

Police said it connected a warehouse on the US side with one in Tijuana, the main gateway for drugs into California.”
