12 Indians killed in quarry collapse after cyclone rains

"So far 12 bodies have been found, we are looking for more," deputy commissioner of Aizawl district Nazuk Kumar told AFP.

Rescue efforts in the quarry were being hampered by "heavy rains", police director general Anil Shukla said, NDTV news network reported.

Mizoram Chief Minister Lalduhoma offered compensation to families of the victims of the "landslide due to Cyclone Remal".

"I pray for the success of rescue and relief operations and wish a speedy recovery of the injured," India's President Droupadi Murmu said on social media.

In Mizoram, several highways and key roads were disrupted by landslides. All schools were shut and government employees asked to work from home.

India's weather office has issued warnings of extremely heavy rainfall across Mizoram and other northeastern states on Tuesday.

In India's neighbouring Assam state, one person was killed and heavy rains had cut the power supply, Chief Minister Himanta Biswa Sarma said in a statement.

The cyclone made landfall in low-lying Bangladesh and neighbouring India on Sunday evening with fierce gales and crashing waves.

Overall, at least 38 people died in the cyclone or storms in its wake.

In India, eight people died in West Bengal state, officials said Tuesday, updating an earlier toll of six, taking the total killed in the country to at least 21.

In neighbouring Bangladesh, which bore the brunt of the cyclone that made landfall on Sunday, at least 17 people died, according to the disaster management office and police.
