The murder of a journalist in Azerbaijan has sent political tensions within the country soaring.Elmar Huseinov, who was the editor of an anti-government magazine, was shot by unidentified attackers outside his home in the capital Baku. Opponents of President Ilham Aliyev have said they plan to turn his funeral tomorrow into a protest against what they claim is his authoritarian rule. In a statement the Interior Ministry said it would do everything necessary to maintain order during the funeral. The Caucasian republic appears to be in its most volatile state since elections in 2003 which brought Aliyev to power, succeeding his father. The vote was criticised by observers as falling short of international standards. The result was greeted with protests in the capital in which two people were killed and scores injured. More than 100 people were arrested. Most have since been released but several opposition leaders were handed jail terms.
