Travel warning issued
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
The U.S. Embassy restricted government travel in Nogales, Mexico, to essential daytime movement on September 5.
The alert sits under Sonora's existing Level 3 advisory, so travelers should check state-by-state.
Background
The U.S. State Department assesses Mexico state by state rather than issuing one blanket grade for the country, and Sonora — where Nogales sits — is currently a Level 3 "Reconsider Travel" area due to ongoing regional conflicts. The U.S. Mission to Mexico issued the September 5 alert limiting government activities and travel in Nogales to essential daytime movements only because of an unspecified threat, and it warned U.S. citizens of a change in security. The city sits directly across the border from Nogales, Arizona, a major crossing. Officials did not publicly disclose the nature of the threat, and a similar August 24 alert had suspended government travel in Mexicali.
