A woman was killed and at least 10 others were injured in two minor blasts in an express train at the Chennai Central Railway Station on Thursday morning.

According to reports, the blasts occurred around 7.30 am in the sleeper coaches S4 and S5 of the Bangalore-Guwahati Express as it entered platform number 9 of the station. Both coaches were damaged in the blasts.

"There were two separate low intensity blasts inside the train. The police are investigating the matter," said Southern Railways General Manager Rakesh Mishra.

The deceased woman has reportedly been identified as Swati, 22, a resident of Guntur in Andhra Pradesh. She was traveling with her relatives. One of the blasts occurred under her seat in the train killing her on the spot.

The Railways announced a compensation of Rs 1 lakh to the family of the woman killed in the blasts.

Two of the 10 injured are critical. All injured were admitted to Rajiv Gandhi Government General Hospital.

While the railway police detained a man who was found hiding in the train with explosives, the National Investigation Agency (NIA) said it is not ruling out the terror angle into the incident.

Police and bomb disposal squads, along with sniffer dogs, rushed to the blast site immediately after the explosions. The entire station area has been cordoned off and train services have been temporarily suspended.

The train had left Guwahati in Assam for Bangalore in Karnataka on Tuesday. It was reportedly running about two hours late.
