'It was a nightmare' says one resident in Kharkiv as houses and cars burn nearby following a Russian drone strike on the major Ukrainian city , killing four people and wounding 17, according to the mayor. The attack came as US, Ukrainian and European officials were in Geneva to discuss a proposal to end the nearly four-year war in Ukraine, which began when Russia launched a full-scale invasion. "We want peace, and we want all this to end quickly" adds local resident Olena Bondarenko. IMAGES AND SOUNDBITES
