Police in western India say at least 30 have been killed and scores of others feared trapped under collapsed buildings as mudslides triggered by monsoon rains continue to lash the region.

Officials in Maharashtra state say worst hit is the area south of the state capital, Mumbai, also known as Bombay, where more than 100 people are feared buried under flattened mud houses.

Authorities have called the army to assist thousands of people stranded by flood and mudslides.

In Bombay, India's financial and entertainment capital, many low-lying areas are flooded.

Weather forecasters say heavy rains and winds will continue for at least through Wednesday.

India's monsoon rains, which usually last from June through September, claim hundreds of lives every year.
