Seventeen Amarnath pilgrims, including two women, were killed and 29 injured when the state transport bus in which they were travelling skidded off the road and fell into a deep gorge at Banihal on the Jammu-Srinagar national highway Sunday afternoon. Police said they were investigating the cause of the accident. “Eyewitnesses gave us different versions. Some said a tyre of the bus burst and the driver lost control. Some said that the brakes didn’t work,” Deputy Superintendent of Traffic Vishal Manhas said.
