Heavy rain triggered a landslide in a densely populated Mumbai slum killing at least 12 people and injuring 25 others, a police official said Friday, AP reported. Around 20 tin-roofed shanties were buried under mud and rocks after a heavy downpour forced a nearby hillside to collapse late Thursday night in Sakinaka, a northeast Mumbai suburb, police constable Babu Uttam Pawar said. Police, firefighters and slum dwellers pulled 25 people from the debris but many others remained trapped under piles of mud and stones, he said. Firefighters and volunteers worked through the night to pull survivors from the mud although their efforts were hampered by incessant rain, Pawar said. Sakinaka is around 23 miles (35 kilometers) from downtown Mumbai, India's financial hub. -- SPA
