Chain reaction panic on thin ice
A chain reaction panic saw nearly a dozen people fall through thin ice into a US lake.
The desperate cries for help began when one man on a sledging excursion in Wrightwood, California, fell through the ice.
Others frantically tried to rescue him, but one-by-one they plunged into the icy water themselves.
Within five minutes from the first crack, nearly a dozen people were fighting for their lives.
It took close to ten minutes, but bystanders helped pull everyone to shore. Fortunately, nobody was seriously injured.
