22 police held following southern Mexico violence

Authorities said Sunday that 22 local police have been arrested following the deaths of six people in the Mexican state of Guerrero.  Unidentified gunman and numerous officers were involved in several violent incidents that killed six people late Friday and early Saturday in Iguala, about 200 kilometers (125 miles) south of Mexico City.  State attorney general Inaki Blanco Cabrera said that three students were killed in two separate incidents. Another three people died in an attack on a bus — a minor who belonged to a soccer team, a woman and the bus driver.
