Russia to hold Central Asia army drills near Afghan border
The insurgents have capitalised on the withdrawal of foreign troops to launch a series of offensives across the country.
Afghan government troops and refugees have in recent weeks crossed into Tajikistan, fleeing Taliban advances.
Alexander Lapin, commander of the Central Military District, said that the troops will run drills to defeat "illegal armed units that invaded the territory of an allied country".
Troops from a Russian military base in Tajikistan and the Central Military District will take part in the games, the defence ministry said.
More than a dozen diplomatic missions in Afghanistan called Monday for "an urgent end" to the Taliban's ruthless military offensive, saying it was at odds with claims they want a negotiated settlement to end the conflict.
