Violent response to Mexico anti-drug cartel operation

At least seven people have been killed and 15 injured across the Mexican state of Jalisco.

Several vehicles have been set on fire in Guadalajara, Mexico's second biggest city.

An army helicopter was also shot at, killing three soldiers and injuring 12 others.
