Abduction, violence and death has long been a constant reality for journalists in conflict regions. The recent beheading of James Foley by the Islamic State (ISIS) as a message to the U.S. is just the latest reminder of that ongoing threat. The Committee to Protect Journalists has a dedicated page for concerns in Syria, the most dangerous country for reporters, and has tried to keep track of the number of journalists missing and killed across the world.

Below are photographs and details about the missing journalists worldwide, according to the CPJ's "missing" page and other sources. Of the most recent 23 journalists listed as missing over the last 10 years, 13 disappeared in Mexico, a stark reminder of the toll of the Mexican drug war. This list starts with the most recent cases. The latest was 10 days ago. The longest unsolved case is 31 years old.
