Nagorno Karabakh: air raid sirens sound in the main city as shelling restarts

Russia and the European Union have stressed the need for Armenia and Azerbaijan to heed the ceasefire in Nagorno Karabakh, as air raid sirens sounded in the main city, Stepanakert. The Armenian authorities in Karabakh say the city is now being shelled again. Azerbaijan's president Ilham Aliyev earlier accused Armenia of a war crime after rockets destroyed housing in Azerbaijan's second city Ganja.
