More than 30 people have been killed in a rail accident in the Indian state of Uttar Pradesh.

The engine and two carriages of the Janta Express, which travels between Dehradun and Varanasi, derailed near the village of Bachhrawan.

More than 40 people were also injured in the accident.

Villagers, police and railway guards are trying to rescue passengers trapped in the carriages, while rail minister Manoj Sinha has launched an inquiry into the incident.

The incident is the latest in a series of disaster for the Indian railway network.

Last month, at least 11 people died after three coaches of the Bangalore-Ernakulam Intercity Express derailed in the southern state of Karnataka.
