German neurologist Karl Max Einhaupl of Berlin's Charite university hospital, who examined the health condition of jailed former Ukrainian prime minister Yulia Tymoshenko, arrives for an interview with Reuters in Berlin April 26, 2012. German President Joachim Gauck has cancelled a planned visit to Ukraine next month, a spokesman said, amid growing concerns over the health and treatment of Tymoshenko. Berlin has offered to treat Tymoshenko, who suffers from acute back pain, in a German hospital, an offer it repeated on Wednesday. It also expressed concern over reports that prison guards beat her during her recent forced move to hospital. REUTERS/Fabrizio Bensch (GERMANY - Tags: HEALTH POLITICS)
