New drug tunnel found near US-Mexico border

TIJUANA, Mexico (AFP) - Mexican authorities said they have discovered a "sophisticated" tunnel likely intended for smuggling drugs and migrants across the US-Mexico border.

The entrance to the tunnel, which was still under construction, is located in a warehouse about 300 metres from the border between the Mexican city of Mexicali and Calexico, California, Mexicali police chief Marco Antonio Carrillo told AFP.

The tunnel - which is about 10 metres deep and 30 metres long - has a ventilation system and lighting and is considered the most "sophisticated" of such structures found in recent years, Mr Carrillo said.

Authorities uncovered it thanks to an anonymous tip, he added.
