At least 30 students were injured, three of them critically, when their school bus rammed into a tree in Uttar Pradesh's Bulandshahr district on Saturday afternoon, police said.
The accident took place in the Khurja Dehat area when the bus carrying the students of the Azad Public School spun out of control and ploughed into the roadside tree.
"All the injured have been admitted to a hospital where the condition of three is stated to be critical," police inspector Ajay Agarwal told reporters in Bulandshahr, some 400 km from Lucknow.
"Those injured are in the age group of 9-14 years. The students were on their way to their homes at the time of the accident," he added.
According to the police, the driver of the bus lost control of the vehicle as he tried to save a cyclist who came in the way.
