MEXICO CITY (AP) — U.S. Ambassador Ken Salazar lashed out Wednesday at Mexico’s failure to accept aid in the fight against drug cartels, claiming the country “closed the doors” on security cooperation.

U.S. Ambassador to Mexico Ken Salazar said AMLO's "hugs, not bullets" strategy failed amid a breakdown in bilateral security cooperation.

Mexico's "hugs not bullets" security strategy of tackling criminal violence at its roots has failed, US ambassador Ken Salazar said Wednesday, in unusually blunt remarks that upset the Mexican government.

The "hugs not bullets" security strategy introduced by Mexico's former president Andres Manuel Lopez Obrador to tackle criminal violence at its roots failed, US ambassador Ken Salazar said Wednesday.
