Seventy journalists have been killed thus far in 2012, according to the International News Safety Institute.
"Journalists are more than ever in the cross-hairs of the enemies of freedom," said INSI director Rodney Pinder.
"Despite some encouraging international political moves to halt the killings, guns and bombs remain the favored method of censorship in far too many countries," said Pinder. "Each and every killing chokes the free flow of information without which free societies cannot function.
The Guardian points out that the majority of deaths happen in countries during supposed peacetime.
"Forty-three journalists died in countries officially at peace, victims mostly of vicious criminals, and often abetted by corrupt security forces, politicians and business interests," the Guardian reports.
