Following the Russian train disaster on Friday evening, the railway line between Moscow and St Petersburg is operating again as normal.
A home-made bomb exploded at 9pm local time, derailing the train, 350 km north of Moscow. It killed 25 people, injured over a 100, and has left 26 still missing.
Vladimir Markin, a spokesman for federal prosecutors said: “Today, since early morning, as soon as it was light, investigators resumed their work at the crash site. They are also working with witnesses. So far, it’s too early to speak about suspects.”
A major intelligence investigation is underway. Family members have been coming to a morgue to identify victims’ bodies.
It is the worst bomb attack in Russia outside the mainly Muslim North Caucasus since a spate of suicide attacks in 2004.
In Moscow, people gathered at a church service to mourn those who died.
There are fears of a terrorist upsurge in Russia’s heartland as speculation grows over who planted the bomb.
