Slovak Prime Minister Robert Fico's condition is stable and he is improving, doctors treating him said on May 20, as he recovers from being hit by four bullets in an assassination attempt last week. "After today's medical board meeting, the patient's condition is stable," the hospital in the central Slovak city of Banska Bystrica said in a statement. Deputy Prime Minister Robert Kalinak said on May 19 that Fico's condition was still too serious for him to be moved to a hospital in the capital, Bratislava. Interior Minister Matus Sutaj Estok said an investigation team had been set up to look into whether the suspect had acted alone.
