March 12. Authorities in the US state of Texas have advised American citizens not travel to Mexico during the spring break holidays for security reasons.
The Texas Department of Public Safety (DPS) said that drug cartel violence represented a significant threat for anyone crossing into Mexico.
It comes after four Americans were kidnapped shortly after crossing the border last week.
Four Americans were kidnapped by a drug cartel, and two of them were murdered, when they visited the town of Matamoros, Mexico, earlier this month. A Mexican bystander was also killed in the shooting.
The cartel responsible has since apologised for the incident and handed over its own gunmen to the police.
