Japan volcano: Mount Ontake eruptions hamper rescuers

Japanese rescue teams have spent a third day searching for survivors on Mount Ontake, trapped by Saturday's eruption.

Recovery efforts have been hampered by conditions as the volcano continues to shoot gas, rocks and ash into the air.

Hundreds of hikers were on the volcano when it erupted - at least 36 people are known to have died.
