Gunmen kill 13 police in daytime ambush in central Mexico

Gunmen killed at least 13 Mexican police in an ambush a short distance outside the capital on Thursday, local authorities said, in one of the worst mass slayings of security forces to rock the country in recent years.

Photos of the grisly scene circulated on social media showing a bullet-riddled police car and an unmarked truck, along with officers' bodies scattered out along the street or still inside the car.

The convoy of security personnel was attacked in broad daylight by suspected gang members in the Llano Grande area in the municipality of Coatepec . . .
