An aerial shot taken from a helicopter shows villagers search for the missing along railroad tracks at Telwatte, about 100 kilometers (63 miles) south of Colombo, Sri Lanka, Wednesday, Dec. 29, 2004. The massive tidal waves that slammed into Sri Lanka flung a train off its tracks, leaving many of its 1,000 passengers dead or missing, police said Tuesday. Rescue workers reported another 3,009 deaths from Sunday's earthquake-triggered tsunami, lifting Sri Lanka's toll to 21,715, said the National Disaster Management Center.(AP Photo/Vincent Thian)
