Russian economic crisis: 'My mortgage is more than my salary'

It is a year since Russia annexed the Ukrainian region of Crimea.

President Vladimir Putin has praised the Russian people's patriotism "in supporting the aspirations of the people of Crimea and Sevastopol to return to their native shores".

But that patriotism has come at a cost.

Over the past twelve months the rouble has lost almost half its value against the dollar, thanks to a combination of the collapse in oil prices and the sanctions imposed by the United States and European Union following the annexation of Crimea and Russia's involvement in the eastern Ukrainian regions of Donetsk and Luhansk.

The BBC's Richard Galpin spoke to man calling himself "Max" - one of the thousands of people who in recent years took out mortgages to buy their flats in US dollars instead of roubles.

The dramatic fall in the rouble against the dollar means his monthly mortgage payments are now more than his salary.
