At least eight girl students and a warden were killed while around 40 students and teachers were injured, many of them critically, after a school bus overturned in Manipur's Bishnupur district on Wednesday, the police said.

The bus carrying the girl students and some teachers suddenly overturned when the driver was negotiating a turn on the Old Cachar Road near Longsai, killing at least five students on the spot and injuring 44 others.

The injured were admitted to different hospitals, where three students and a school warden succumbed to their injuries.

The death toll is likely to increase as the condition of many of the injured students is stated to be critical.
