Baghdad: Iraq remained worst when it came to punishing murders of reporters despite violence against media rose sharply in Mexico in 2010.

Committee to Protect Journalists (CPJ) said the war-wracked country topped the list. It was published by the New York-based press watchdog to spotlight countries where media killings often go unpunished.

The CPJ, whose "Impunity Index" calculates the number of unsolved murders of reporters in each country per one million residents, noted grimly that "the countries at the top of the index -- Iraq, Somalia and the Philippines – showed either no improvement or even worsening records."

Overall, 13 countries made the list with five or more unsolved journalist deaths from 2001 until the end of 2010.

Iraq, which has sat at the top of the list since the CPJ first compiled it in 2008, had 92 deaths, equating to a rate of 2.921 unsolved media murders per one million residents.

Somalia, with 10 unsolved murders, was next with 1.099, while the Philippines was third with 56 deaths and a rating of 0.609.

The rest of the list included Sri Lanka with nine unpunished media killings, Colombia with 11, Afghanistan with seven, Nepal with six, Mexico with 13, Russia with 16, Pakistan with 14, Bangladesh with five, Brazil with five and India with seven.
