India's Prime Minister Narendra Modi has vowed to punish whoever was guilty in causing the deadly train crash, which occured on Friday. He stated that people found guilty over the deadly accident will be "punished stringently".

The incident on Friday involving two passenger trains and a goods train in Odisha state resulted in at least 288 fatalities and more than 900 injuries.

Rescue efforts have concluded, with officials saying all trapped and injured passengers have been retrieved.

Mr. Modi visited the scene, labelling the incident a "painful" one. He also met victims of the disaster in hospital, and vowed that his government would leave "no stone unturned for the treatment of those injured".

However, it is still not clear what caused the multi-train collision in Balasore district, which has been described as India's worst rail accident this century.

A thorough investigation has been launched, but a preliminary report indicates that the accident was caused by signal failure, according to KS Anand, chief public relations officer of the South Eastern Railway.

Around 2,000 passengers are believed to have been on board the two passenger trains involved, which were involved in the multi-train collision in Balasore district, which has been called India's worst rail accident this century.
