This week marked the first annual International Day to End Impunity for Crimes against Journalists.
Reporters and media workers across the world face imprisonment, kidnapping, being deliberately targeted and several other dangers whilst doing their jobs, and the situation in some countries is getting worse.
While the image of the foreign correspondent is a glamorous one, the reality is that the people in most danger are local reporters and fixers who assist foreign news teams - 94 per cent of those killed are locals.
Sadly, killed journalists' governments are often lax about bringing their murderers to court, and sometimes even play a role in their deaths, leaving their families without justice.
While the most journalists die in conflict zones such as Syria and Pakistan, one in five die for investigating drug and crime rings in Latin America.
Over the past decade, more than 700 journalists have been killed on the job - and shockingly, only one in ten cases worldwide has led to a conviction.
In a statement, UN Secretary General Ban Ki-Moon said:
Together, we must end the cycle of impunity and safeguard the right of journalists to speak truth to power.
Impunity for crimes against journalists is a "vicious cycle", he continued, creating an environment which emboldens would-be perpetrators of violence and has a chilling effect on the media.
