At least 40 people, mainly women, were injured when an HRTC bus they were travelling in hit a hillside on the Byasa-Bakhli road in Himachal Pradesh’s Kullu district on Friday afternoon, officials said.

About 60 people were onboard when the accident took place near Katar village. Chief Medical Officer Kullu Ajay Thakur said the accident occurred around noon and 40 people were brought to the Regional Hospital Kullu for treatment. Prima facie, the accident appears to have been caused by brake failure, officials said.
