At least 22 people were killed in a string of attacks in Mexico including a shooting at a bar in Monterrey just hours after the opening of soccer's Under-17 World Cup.

Gunmen stormed the bar in Mexico's third largest city  and executed three people,  wounded another, and kidnapped a security guard at the bar who was later found dead. Four other people, 18-25 years old, were killed Sunday morning in Guadalupe. Monterrey is one of the host cities for FIFA's Under-17 football tournament and it held two matches on its opening day Saturday.
