Russia marks on Friday the 80th anniversary of the Soviet and allied victory over Nazi Germany, though there are fears that Ukraine may seek to disrupt the most hallowed celebration in the Russian calendar.

Ukraine attacked Moscow with drones for a third day on Wednesday forcing most of the Russian capital's airports to close just as Chinese President Xi Jinping was due to arrive to mark the victory over Nazi Germany in World War Two.

Russia and Ukraine continued air strikes against each other’s capitals overnight, including an attack that killed two people in Kyiv, as Moscow prepared to host the leaders of China, Brazil and other states to commemorate the end of World War II.
