CHIANG RAI, Thailand (Reuters) - Four of 12 Thai schoolboys were rescued from a flooded cave on Sunday in a daring and dangerous operation to save the children and their soccer coach who have been trapped underground for more than two weeks.

The operation to rescue the remaining eight boys - some as young as 11 and weak swimmers - and the coach was called off at nightfall until Monday to give the divers time to replenish oxygen supplies and ensure all preparations were complete.
