Unstable Rocks Delay Japan Tunnel Rescue

Anguished relatives fought back tears Thursday after being told they must wait even longer for workers to reach 20 people trapped for more than five days inside a crushed mountain tunnel.

Workers could see a bus flattened to 3 feet high, but large teetering rocks were hampering efforts to reach it.

There was almost no hope of finding survivors in the freezing cold. The bus, with 19 people inside, was flattened when a rock the size of a 20-story building peeled off the mountainside Saturday and smashed through the tunnel roof.
