On 9 April 2021, the U.S. Consulate General in Tijuana issued a Security Alert, which reads in part as follows: “Travelers should exercise increased caution when traveling in and around Mexicali, the Mexicali Valley, and the western part of the state of Sonora due to the possibility for heightened violence between rival cartel factions. Members of the embassy community have been advised to avoid the Mexicali area until further notice.”
