URDA, Spain (AFP) -- Residents and local officials gathered Saturday in a Spanish village near the site of a high-speed train collision that killed at least 69 people for a memorial Mass honoring the victims. The pews inside the San Juan Bautista church in Urda, in the central province of Toledo, were packed, while dozens more people gathered outside to listen to the service. Some wiped away tears. Investigators are looking into the cause of one of Europe's deadliest rail disasters this century,
