A 29-year-old groom was injured as unidentified assailants opened fire at him during his wedding procession, the police said on Tuesday.
The incident took place on Monday evening. The groom, Rajiv, sustained a gunshot injury on his chest, Inspector Ravisher Singh said.
He was rushed to a private hospital where his condition was stated to be critical, the officer said.
Police said an investigation is underway in the case.
The incident occurred in the S10 coach of the Delhi-bound Sapt Kranti Express near Kaptanganj -- around 40 km from Gorakhpur junction -- on Monday evening, the police said.
Rajnath Singh said as far as the NDA government is concerned there will not be discrimination against anybody.
It is also practically not possible to ascertain the antecedents and genuineness of all the devotees visiting Sabarimala, the government said.
"We have put an end to the loot of public money. We stopped siphoning of Rs. 90,000 crores," PM Modi said in Odisha.
To ensure that this happens as projected, it is a pre-requisite that India has a decisive leadership, consistency in policy direction and a strong and stable government.
Kanakadurga, who had been in hiding for the last two weeks after the darshan of Lord Ayyappa at the Sabarimala shrine due to security reasons, reached home in Perinthalmanna on Tuesday morning.
