At least 10 people are reported to have been killed in an explosion on a trolleybus in the Russian city of Volgograd. The blast comes a day after a suspected suicide attack killed at least 17 people in the same city.
The reports said the blast completely destroyed the vehicle, a common form of transport in Russian cities, and broke windows in nearby buildings.
The explosion comes a day after a suspected suicide attack at Volgograd’s main railway station killed at least 17 people. The death toll rose from 16 overnight when one of the people injured in the attack died of his wounds, hospital officials said.
Investigators say they believe Sunday’s attack was carried out by a female suicide bomber.
Sochi security fears
The attacks come amid heightened concerns about security for the Winter Olympic Games to be held in the Russian Black Sea resort of Sochi in just six weeks’ time.
Sochi is in direct proximity to the volatile North Caucasus region, which sees almost daily violence in the course of an Islamist insurgency.
Although no group has immediately claimed responsibility for the Volgograd attacks, there has been much speculation that Islamist militants active in the North Caucasus region may be behind such attacks, after their leader, Chechen warlord Doku Umarov, called on supporters in July to “do their utmost to derail” the Games.
Monday’s attack is the third such attack in Volgograd in two months. In October, six people were killed in a suicide bombing on a bus.
Russia’s interior ministry said on Sunday it was stepping up security at all the country’s main train stations and airports.
