Himachal Pradesh railway bridge collapse: A railway bridge on the Chakki river in Kangra district collapsed on Saturday as torrential rains caused a heavy flow of water and monsoon. The 800-meter-long narrow gauge route, built during British rule, collapsed after the heavy flow of water weakened the pillars. At least 21 people are believed to have lost their lives while several others are reported missing as heavy rains triggered landslides and flash floods in several districts of the hill state.
