MUMBAI: Heavy monsoon rains triggered a landslide in a densely populated neighborhood in India’s financial capital, Mumbai, early Wednesday, killing at least six people and injuring four others, authorities said.

The landslide struck before dawn when a section of hillside collapsed onto two or three homes in a tightly packed cluster of houses in Mumbai’s suburb of Ghatkopar, said Tanaji Kambli, a civic official.

Authorities immediately launched a rescue operation involving firefighters, police, the National Disaster Response Force and civic officials but efforts were hampered by narrow access lanes that prevented the use of heavy machinery, officials said.

Rescue teams pulled at least 10 people from the debris and rushed them to a government hospital. Six people, including two children and two teenagers, were declared dead on arrival, Tanaji said. Four others were hospitalized and were receiving treatment.

Ritu Tawde, the mayor of Mumbai, visited the area and announced monetary compensation for the families of the victims.
