Four persons, including three Indians, were killed and 40 others injured when a bus carrying them met with an accident in Abu Dhabi, police said.
"The bus driver lost control over the speeding vehicle and then swerved suddenly, despite there being no sudden curves in the road," said Lt Yousef Al Bahlouli, head of the Abu Dhabi Police Traffic Accident Investigation Unit.
Three of the passengers, all Indians, died on the spot. The bus driver, a Pakistani, was declared dead on arrival at the local Al Mafraq Hospital.
Of the 50 passengers on the bus, 26 Indian and one Bangladeshi were taken to hospital. One was admitted for spinal injuries and is in critical condition.
Others suffered mild injuries and have been discharged from hospital.
The bus was transporting labourers from Mussafah to Abu Dhabi, where they were to be dropped at a construction site.
