A media watchdog says in a report released Monday that 105 journalists were killed while working in 2010.
The chief of Press Emblem Campaign says the killing of journalists has become an epidemic with no cure.
Blaise Lempen, secretary-general of Press Emblem Campaign, says the international community has been unable to establish "effective mechanisms" for bringing the responsible parties to trial.
The report says Mexico and Pakistan are the two most dangerous countries for media work, with 14 journalists killed in each country this year.
The media watchdog group says fewer fatalities have been reported this year compared to 2009, when 122 journalists died, but this year's toll is still higher than the 91 deaths recorded in 2008.
