Since this says that Mexico reported them, why didn’t it say, “tunnels leading from the United States into Mexico?”
Can you imagine their rage if our special forces used some of these tunnels to sneak into Mexico and do bad things to the drug lords?
They know which direction Sinaloa’s traffic flows.
Since one was unfinished they assumed both were started in Mexico. You could be correct. They dug the tunnel from the U.S. to Mexico to attack drug lords at night, and the tunnel coming back was their second avenue of escape. /sarcasm
