Uttar Pradesh Chief Minister Yogi Adityanath on Thursday rushed to Kushinagar and met the families of the victims killed in a major bus accident that took place early morning. Thirteen students, in the age group of 8 to 10 years, were killed while at least four are critically injured after their school van was rammed by a Gorakhpur-bound train at an unmanned railway crossing. The Chief Minister said strict action would be taken against those found guilty while adding that the driver of the van, prima facie, appears to have caused the accident as he was wearing earphones at the time. He also raised questions over the age of the driver. "I spoke to the Rail Minister this morning. Prima facie, it appears to be the fault of the van driver. He was driving with his ear-phones. Even things have come forward regarding his age," Adityanath said.
