Italian alps glacier collapse: search resumes for missing hikers after six killed

Fifteen climbers could still be missing, say authorities, after fall of ice, snow and rock on popular trail on Marmolada mountain in Dolomites

The search for survivors of a glacier collapse in which at least six people have died has resumed in Italy's Dolomites region.

Authorities believe as many as 15 people may still be missing after a large chunk of alpine glacier broke loose on Sunday afternoon and sent ice, snow and rock slamming into hikers on a popular trail on the Marmolada peak. Nine people were injured in the slide.
