The UN body monitoring press freedoms says instabily in the Middle East after the Arab Spring have contributed to an increase in the number of journalists killed in recent years.

In a report published on Tuesday, UNESCO stated that 430 journalists were killed between 2007 and 2012. In 2012, UNESCO said 121 journalists were killed, over double the 59 that died in 2007. According to this report, “uprisings in parts of the Arab region” were behind a rise in deaths in conflict-zones. The report added that Syria, ravaged by a civil war since 2011, is the most dangerous place to work. UNESCO described the killing of journalists as “the ultimate form of censorship.” A recent report from Reporters Without Borders says fewer journalists were killed in 2013 than 2012, but more were kidnapped.
