Three security force members have died in clashes in the state of Sinaloa after the arrest of a son of notorious Mexican drug kingpin "El Chapo".
Ovidio Guzmán-López - himself alleged to be a leader of his father's former cartel - was captured in Culiacán and transferred to Mexico City.
Furious gang members set up road blocks, set fire to vehicles and attacked a local airport.
Two planes were hit by gunfire - one while preparing to take off.
More than 100 flights were cancelled at three Sinaloa airports.
The state governor said earlier 18 people had been admitted to hospital.
Mr Guzmán-López - nicknamed "The Mouse" - is accused of leading a faction of his father's notorious Sinaloa cartel, Defence Minister Luis Cresencio Sandoval said. It is one of the largest drug-trafficking organisations in the world.
Hi father, Joaquín "El Chapo" Guzmán, is serving a life sentence in the US after being found guilty in 2019 of drug trafficking and money laundering. His trial revealed some of the brutal details of how Mexico's drug cartels operate.
