Sharjah 24 – AFP: At least 19 people were killed when monsoon rains caused a four-storey building to collapse in the Indian megacity of Mumbai, authorities said Tuesday.

The structure -- located next to a slum in a central city district -- collapsed just before midnight on Monday, according to local officials.

Fourteen people had been rescued by Tuesday evening but emergency workers retrieved 19 bodies from the rubble.

"Search and rescue operations are continuing," a spokesperson for the National Disaster Response Force told AFP.

At least six of those killed were between 18 and 21 years old, city authorities said.

Heavy rainfall was hampering operations as rescuers moved concrete slabs and sifted through mud and rubble searching for survivors.

Monsoon rains from June to September are vital to replenishing rivers and groundwater in India but the deluge also causes widespread destruction.

Building collapses are common during this period, with old and rickety structures buckling under days of non-stop rain.

Maharashtra state minister Aaditya Thackeray urged residents to evacuate other similarly "dilapidated" buildings.

The western state of Maharashtra, of which Mumbai is the capital, was hit badly last year when monsoon-triggered floods and landslides killed 200 people and forced a quarter of a million to evacuate their homes.
