Share this article Share The two sides accused each other of targeting civilian areas, as the conflict widened a week after heavy fighting broke out in the decades-old dispute over the ethnic-Armenian region.More than 220 people are thought to have died in the conflict during the past week. Armenia and Azerbaijan have resisted international calls for a ceasefire and clashes have intensified in recent days, with both sides claiming victories on the front and saying they are inflicting heavy losses. In a fiery address to the nation, Azerbaijani President Ilham Aliyev set conditions for a halt to the fighting that would be near-impossible for Armenia to accept.He said that Armenian forces 'must leave our territories, not in words but in deeds' and provide a timetable for a full withdrawal.Yerevan must also recognise the territorial integrity of Azerbaijan, apologise to the Azerbaijani people and admit that the region is not part of Armenia, Aliyev said. President Ilham Aliyev said: 'Nagorno-Karabakh is our land. We have to go back there and we are doing it now. 'This is the end. We showed them who we are. We are chasing them like dogs.'

HOW DID THE CONFLICT START?Long-simmering tensions between Christian Armenians and mostly Muslim Azerbaijanis began boiling over as the Soviet Union frayed in its final years. Once the USSR collapsed in 1991 and the republics became independent nations, war broke out.A 1994 cease-fire left Armenian and Azerbaijani forces facing each other across a demilitarised zone, where clashes were frequently reported.
