LOS ANGELES, May 18 (Xinhua) -- A man opened fire at a church festival Saturday in California, wounding his ex-wife and two others nearby, police said.

    The man shot with a 22-caliber rifle a few minutes before an annual weekend festival was to begin on a grassy field at the St. John Baptist de la Salle Roman Catholic parish, police said.
