Four of the victims of a recent terrorist attack in southern Russia will receive medical treatment in Moscow, a local medical official said Wednesday.
At least 30 people were injured after a Lada car exploded on Tuesday near a small restaurant in the centre of the southern Russian city of Pyatigorsk on Tuesday.
"Four out of six victims in serious condition will be transferred to Moscow because they need a hi-tech treatment," the source told RIA Novosti.
A criminal case has been launched on charges of terrorism, said a spokesman for the Russian investigations committee said.
President Dmitry Medvedev ordered the head of the Russian Federal Security Service (FSB) to do everything possible to get to the bottom of the incident.
Pyatigorsk is the capital of Russia's North Caucasus Federal District, which includes the volatile republics of Chechnya, Dagestan and Ingushetia, where terrorist attacks and militant clashes are common.
