Mexican policeman killed in taco stand attack

Gunmen killed a policeman and a 15-year-old boy when they opened fire and hurled a grenade at a crowded taco stall in a Mexican city.

The policeman was shot while eating with a fellow officer at the stall in Uruapan, a city plagued by drug violence.

Before fleeing, the attackers shot two tanks of gas that exploded, burning the teenage taco stand worker to death, police said. Four other people were injured.

Investigators said the attack apparently targeted the two officers.
