Three states, three warnings: Why the US urges travelers to stay away from Colima, reconsider Jalisco, and only be cautious in Nayarit
On a December evening in 1988, Pan Am Flight 103 exploded over Lockerbie, Scotland. Two hundred and seventy people died. In the aftermath, a devastating truth emerged: U.S. embassy staff in Moscow had been warned of a terrorist threat against Pan Am flights a week earlier. That warning was posted on an internal embassy bulletin board, but never shared with the traveling public.
