(CNN) -- Violence in and around the Mexican city of Ciudad Juarez on Friday and Saturday left 23 people dead, including two police officers ambushed while on routine patrol, authorities said.
A gunman opened fire on Friday after a car blocked the officers' truck, said Arturo Sandoval, a spokesman for the district attorney's investigative unit.
In another incident, a group opened fire in a park full of visitors, killing a man and wounding at least six bystanders.
Later on Friday, a young couple was fatally shot as they drove through a part of the city known for its upscale nightclubs.
