A Lenin statue at Lenin Square in Donetsk. Next to the statue, activists have set up a tent flying the Russian flag. Donetsk is the largest city of the Donets Basin (Donbas) region, an area that is the centre of Ukraine's coal mining and steel industry. The Donbas region used to be the power base of Viktor Yanukovych, the now deposed former president, who has fled to Russia where he is being supported by the Russian government as the rightful head of state of Ukraine. Lately Pro-russian protests in the eastern part of the country are calling for greater autonomy from Kiev and a referendum on secession from the western part of the country.
