At least 70 feared trapped in India building collapse: police
The building comprised 47 flats, police in the town of Mahad -- 120 kilometres (75 miles) south of Mumbai -- said in a statement.
The cause of the accident was not clear but building collapses are common during India's June-September monsoon, with rickety structures buckling under the weight of non-stop rain.
"Fifteen injured people have been rescued and taken to hospital," Mahad police said.
The monsoon plays a vital role in boosting agricultural harvests across South Asia. But it also causes widespread death and destruction, unleashing floods, triggering building collapses and inundating low-lying villages.
The death toll from monsoon-related disasters this year has topped 1,200, including more than 800 lives lost in India alone.
