Mexican President Claudia Sheinbaum said Monday she would demand explanations after four U.S. Embassy and Mexican officials died in an accident over the weekend, adding she had been unaware of collaboration between the U.S. and the local government in northern Chihuahua.
Sheinbaum said she wanted to ensure no laws were broken after Sunday's deaths, which the state attorney general said occurred while the officials were returning from an operation to destroy clandestine laboratories in a rural area.
