A human chain of rescuers is searching for survivors a day after a building collapsed in the Indian city of Mumbai, killing 13 people and trapping dozens.

Officials say rescue efforts have been hampered by a warren of old streets which prevent access by heavy vehicles.

Rescuers are hopeful of finding more people alive. A woman was saved on Wednesday but her two children died.

Such disasters are not uncommon in Mumbai, which has thousands of old, dilapidated buildings.

Rescuers are facing a huge challenge because Dongri – in the south of the city, where the building was located – is a web of cramped, narrow lanes, hemmed in by run-down buildings.
