Afghanistan has been facing instability for many years, with government troops fighting against Islamic extremists and terror organizations, in particular the Taliban radical movement and the Daesh terrorist group, both banned in Russia. The Taliban is in control today of more territory than in 2002, when it was ousted from power in a US-led invasion.
