The opposition in Azerbaijan is calling for answers after the murder of an investigative journalist. The situation has prompted parallels with the recent history of Ukraine, a fellow former Soviet republic. Elmar Huseinov, 38, was an outspoken critic of the Azerbaijan elite. He was shot dead on Wednesday, sparking public outrage. Today, as mourners paid their respects at his coffin, the father of the slain magazine editor spoke out.He said his son had been threatened and it was very clear why he was killed. Amid accusations that the government was behind the assassination, today’s funeral in the capital Baku was declared a protest at the rule of Ilham Aliyev. He succeeded his late father as president after a disputed election two years ago. He has denied that the authorities had any involvement in the murder. Many remain unconvinced. One opposition leader has issued an ultimatum to Azerbaijan’s dynastic ruler. He warned him to find the man’s killers within two weeks or resign.
