Mexican police and soldiers have discovered two tunnels in the border city of Tijuana that lead into California.
The tunnels were found in an area of warehouses across from Otay Mesa.
Prosecutors said Monday that one of the tunnels reached to San Diego, California, and the other was unfinished.
The Attorney General's Office said the tunnels were apparently used by the Sinaloa drug cartel to move drugs into the United States.
It said it found the tunnels after the U.S. consulate in Tijuana determined the tunnels were being reactivated after apparently falling into disuse.
