Russia launches counter offensive

New operation meant to halt advancing Ukrainian troops

MOSCOW:

Moscow on Saturday mounted a "counter-terror operation" in three border regions adjoining Ukraine to halt Kyiv's biggest cross-border offensive in the two-and-a-half-year conflict.

Ukrainian units stormed across the border into Russia's western Kursk region on Tuesday morning in a shock attack and have advanced several kilometres, according to independent analysts.

Russia's army has rushed in extra troops and equipment, including convoys of tanks, rocket launchers and aviation units -- though neither side has given precise details on the extent of the forces they have committed.

At least 3,000 civilians have been evacuated from Russian border areas, where emergency aid and medical supplies have been ferried in, while extra trains to the capital Moscow have been put on for people looking to flee.

"The war has come to us," one woman who fled the border zone told AFP at a Moscow train station on Friday, declining to give her name.

Russia's army said Ukraine initially despatched around 1,000 troops, and more than two dozen armoured combat vehicles and tanks -- but it has since claimed to have destroyed around five times as many pieces of military hardware.

AFP could not verify those numbers and both sides have repeatedly been accused of inflating the number of enemy losses while downplaying their own setbacks.

Russia's national anti-terrorism committee said late Friday it was starting "counter-terror operations in the Belgorod, Bryansk and Kursk regions ... in order to ensure the safety of citizens and suppress the threat of terrorist acts being carried out by the enemy's sabotage groups."

Security forces and the military are given sweeping emergency powers during "counter-terror" operations.

Movement is restricted, vehicles can be seized, phone calls can be monitored, areas are declared no-go zones, checkpoints introduced, and security is beefed up at key infrastructure sites.

The anti-terrorism committee said Ukraine had mounted an "unprecedented attempt to destabilise the situation in a number of regions of our country."

It called Ukraine's incursion a "terrorist attack" and said Kyiv's troops had wounded civilians and destroyed residential buildings.

The health ministry said Friday that 55 civilians were in hospital, 12 in a serious condition.

Several Russian media outlets shared a video purporting to show residents from the Sudzha district of Kursk, where Ukraine's offensive has focused, appealing to President Vladimir Putin for help, warning that many were unable to evacuate.
