Nine people, including eight children, were killed and 15 others were injured when a pickup van collided with a mini truck in Uttar Pradesh's Hapur district, the police said today.

The injured were rushed to a hospital where doctors declared nine people, including eight children, dead, the police said.

The 15 injured are undergoing treatment.

Six of the children have been identified as Aksha, Sufiyan, Anas, Gayyur, Shifa and Abdul Rehman. The police said the children were in the age group of 8 to 14 years. A 20-year-old man was among those killed in the accident.

The bodies, after postmortem, were sent to Salepur Kotla village.
