Safeguards for media workers must be strengthened to protect not only their work, but their lives, United Nations (UN) Secretary-General Ban Ki-moon said Monday to mark the International Day to End Impunity for Crimes Against Journalists.

More than 700 reporters and other media workers have been killed in the past decade “simply for bringing news and information to the public,” Ban said on Monday. But the risks they face go far beyond war zones—and are just as often homegrown.

“Many perish in the conflicts they cover so fearlessly. But all too many have been deliberately silenced for trying to report the truth,” Ban said. He called for collective action to “end the cycle of impunity and safeguard the right of journalists to speak truth to power.”

Only 7 percent of crimes against journalists are ever solved, and less than one in 10 is ever fully investigated—sowing fear among media workers and fueling global governments’ powers of censorship, the UN noted in its statement honoring those killed in the line of duty.

“The near complete impunity for the perpetrators of crimes against journalists goes against everything that we stand for, our shared values, our common objectives,” said UNESCO director-general Irina Bokova.

Ban continued, “We must do more to combat this trend and make sure that journalists can report freely. Journalists should not have to engage in self-censorship because they fear for their life.”

The UN’s periodic call for stronger protections for media workers has prompted little progress in countries where killings and censorship are an epidemic, the Committee to Protect Journalists (CPJ) reported last October.
