MOSCOW, January 31. /ITAR-TASS/. Special cross-country vehicles of the Federal Medico-Biological Agency are sent to federal roads in the Rostov Region to provide medical care for drivers and passengers who remain blocked in kilometers-long lines in severe frost.

Four medical teams have been sent to the roads, following the order of the agency's chief Vladimir Uiba. The cross country vehicles are capable to break through snow drifts. The teams are ready to provide medical care right at the sites. If necessary, some people will be evacuated to hospitals, the agency's press service cites the chief as saying.

Two teams were sent from a centre in the city of Lermontov and other two from the agency's southern regional centre. Specialists will be working on the Rostov-Moscow, Rostov-Taganrog, Pyatigorsk-Budyonovsk and Mineralnye Vody-Armavir roads.

The four teams will be on a 24-hours duty to render medical aid on the roads and at emergencies ministry stations.

A government commission working group headed by Emergencies Minister Vladimir Puchkov arrived on Friday in the Rostov Region, where the governor declared a state of emergency on Thursday because of the unusually severe cold and heavy snowfall consequences.

The minister planned to study the situation on the M-4 Don and M-23 Rostov-Taganrog-Mariupol federal roads and visit some residential areas, a spokesman for the ministry said on Friday.

Puchkov also planned to check the work of temporary facilities opened to warm and help drivers and passengers on roads.

As was reported, the minister would hold a meeting of the working group at a station in the Aksai district with the participation of the Rostov Region's Governor Vasily Golubev to discuss actions to solve transport traffic problems.

The governor declared a state of emergency on January 30, assuring that consequences of the severe cold weather would be eliminated in five days.

A heavy month-level snowfall hit the Rostov region from January 28 to 29, seriously affecting 13 of the region's 55 districts, including Rostov-on-Don and Taganrog. The temperature dropped to 30 degrees below zero, with winds of up to 20 m/sec. The severe weather caused jams on roads and impeded public transport work in Rostov-on-Don. There were problems with deliveries of food products to stores.
