A bus careered off one of India's busiest roads early Monday killing at least 29 people, police said.
The driver of the bus was suspected to have fallen asleep before the double-decker bus hit a divider and fell into a gap between two flyovers on the Yamuna expressway from Delhi to Agra, according to police.
The bus was taking about 50 people from New Delhi to Lucknow, in Uttar Pradesh state, when the accident happened at about 4.15am.
It fell more than 12 metres (40 feet) into a river below the road, crushing the top deck of the bus and water was complicating rescue efforts, police said.
"Twenty nine persons have died and 18 others are injured," said Agra district magistrate N.G. Ravi Kumar at the scene of the accident.
The 165-kilometre (100-mile) Yamuna expressway from Delhi to Agra is India's longest six-lane highway and about 900 people been killed on the road since it opened in 2012, according to authorities.
Indian roads are among the world's deadliest, with 464,910 accidents in 2017 that killed nearly 148,000 people, the latest government data shows.
