Nevsky Express bombing: A bomb explodes on the Nevsky Express train between Moscow and Saint Petersburg, derailing it and causing 28 deaths and 96 injuries.

The 2009 Nevsky Express bombing occurred on 27 November 2009 when a bomb exploded under a high speed train travelling between the Russian cities of Moscow and Saint Petersburg causing derailment near the town of Bologoye, Tver Oblast (approximately 200 miles or 320 kilometres from Moscow), on the Moscow–Saint Petersburg Railway. The derailment occurred at 21:34 local time (18:34 UTC). Russian officials had stated that 39 people were killed and 95 injured but later retracted that estimate. 27 deaths had been reported by 2 December. A second bomb exploded at the scene of the investigation the following day, injuring one. It was reported to have been triggered by a remote mobile phone.The first respondents were residents of Lykoshino, a nearby village. A field hospital was set up to treat the wounded and at least 50 were hospitalised in Saint Petersburg. It is believed that, at the time of the derailment, the Nevsky Express was carrying 661 passengers in 13 carriages, of which the last four were thought to have been affected by the incident. Initial reports blamed an electrical fault for the derailment, but investigation showed that the derailment may have been caused by an act of terrorism; a crater was found in the ground near the crash site.The government confirmed that the accident was caused by terrorists, making this attack Russia's deadliest outside the North Caucasus region since the 2004 Russian aircraft bombings.
