At least 23 people have died, 1,000 residents have been evacuated and some public services have been suspended as India’s largest city, Mumbai, experiences its worst rains in over a decade.

Twenty people were killed Tuesday when a retaining wall collapsed onto huts in a settlement in the north Mumbai suburb of Malad, Mumbai’s civic authority said. Three others drowned along flooded roads in the Malad area, disaster management spokesman Tanaji Kamble told CNN.

Search and rescue operations continued Tuesday at the wall collapse site as people were feared trapped inside the rubble, Mumbai fire brigade chief Prabhat Rahangdale told CNN. Sixty-eight people injured in the collapse were treated at hospitals, Kamble said.

“Pained to know about the loss of lives in (the) Malad wall collapse incident,” Devendra Fadnavis, the chief minister of Maharashtra state, where Mumbai is located, tweeted. “My thoughts are with families who lost loved ones.”

About $7,260 will be given to the families of each of those who died, he said.

Heaviest rains in a decade

Although Mumbai experiences monsoon season every year, rain on Monday and Tuesday was the heaviest in more than a decade.

In the 24 hours ending Tuesday morning, Mumbai experienced 375.2 mm (14.77 inches) of rain, the highest total in a 24-hour period since 2005, when Mumbai received 940 mm (37 inches) of rain within 24 hours, according to K. S. Hosalikar, deputy director general at the Mumbai unit of the India Meteorological Department.

Although the monsoon is expected to continue over the next few days, it is not expected to be as intense, Hosalikar added.

The monsoon has been slow to progress across India so far this year, running about two weeks behind schedule and more than 30% behind in rainfall for the entire country so far since June 1, according to data analyzed by CNN Weather.
