3 police officers killed, 10 others wounded in "unprecedented" explosives attack in Mexico

Three police officers were killed and 10 other people wounded Tuesday in an "unprecedented" explosives attack in the Mexican state of Jalisco, the state governor said.

Police officers and staff from the state prosecutor's office "suffered a cowardly attack with explosive devices, which preliminarily caused the death of three colleagues from the municipal police and the Prosecutor's Office, as well as 10 people injured," Governor Enrique Alfaro said on Twitter.

"This is an unprecedented event that shows what these organized crime groups are capable of," the governor said. "This attack also represents a challenge against the Mexican state as a whole."
