Emergency teams pulled 11 more bodies from the rubble of a collapsed building in southern India overnight, but had not given up hope of finding survivors of the weekend tragedy, officials said Wednesday.

Karuna Sagar, a senior officer with the Tamil Nadu state police force, said the confirmed death toll from the disaster on the outskirts of Chennai now stood at 42. At least five people were still unaccounted for.

Emergency workers Tuesday pulled out three more survivors from the rubble of a collapsed building in southern India as authorities said they expected to wind up rescue efforts.

While the death toll from Saturday's disaster on the outskirts of Chennai rose to 28, officials said more than a dozen people were still believed to be trapped in the debris.

The confirmed death toll from India's latest building collapse rose to 17 on Monday as authorities blamed shoddy construction for the tragedy near the southern city of Chennai.

As rescuers extended their search through the rubble of the 11-story complex into a third day, officials said the death toll had risen by six from their last update.   

Rescuers searched desperately for survivors Sunday after an 11-story residential block collapsed in heavy rain in southern India, killing at least 11 people and possibly trapping dozens.

The accident late Saturday was India's second deadly building collapse in one day, after a dilapidated apartment block crumbled in the capital New Delhi, killing ten people including five children.

The death toll in a massive explosion on a state-owned gas pipeline running through southern India has risen to 19, officials said Sunday, while police confirmed a case of negligence was filed against the company.

A senior official from the East Godavari district of Andhra Pradesh state, where the blast occurred Friday, told Agence France Presse that the death toll was expected to rise further as some of the injured remained in critical condition. 

A dilapidated apartment block collapsed in New Delhi on Saturday, killing at least ten people including five children in the country's latest building disaster, reports said citing police officials.

Rescuers scrambled to find survivors after the four-story residential building crumbled, with scores of people feared trapped under the debris.

Five people were killed and at least two injured Saturday in a gas explosion at Asia's largest ship-breaking yard on the west coast of India, police said.

The accident occurred as a group of laborers were breaking up a ship at a yard in Alang, in the state of Gujarat.

A massive explosion Friday on a state-owned gas pipeline running through the southern Indian state of Andhra Pradesh killed at least 16 people and gutted scores of homes, a state minister said.

"At least 16 people are dead. We have recovered 13 bodies so far," state home minister N. Chinna Rajappa told AFP after the blast near a refinery in the East Godavari district.

New Indian Prime Minister Narendra Modi's promises to revive the economy face a gathering threat from inflation, which is creeping up again due to oil prices, weak monsoon rains and hoarding, analysts say.

Food inflation, one of the reasons voters resoundingly ejected the previous Congress government in elections in April and May, is gathering pace with troublesome onion prices in the spotlight.

Four people were killed when a train derailed in eastern India on Wednesday, the latest in a series of deadly disasters to blight the country's dilapidated rail network.

While the rail board initially pointed the finger of blame at Maoist insurgents, police and government officials said there was no reason to suspect sabotage.
