Jolly Christmas descends on Russian capital
At least 1,000 people have gathered for the service at the Church of Immaculate Conception, which is popular with Catholic believers in Moscow.
Here there are many children gathering for the traditional mass conducted in Russian, followed by two more services, in Polish and Russian.
Christmas services are being held all across Moscow in English, Armenian, Spanish, Italian, German and a number of other European and Asian languages.
In about two weeks, on January 7, Russia will celebrate Orthodox Christmas.
