A security camera is seen covered in a floral drape during a media tour of the March 26 Electric Cable Factory in Pyongyang on May 6, 2016. When one of the world's most secretive states opens the door to the international media, it keeps a firm grip on the handle. Some 130 journalists flocked to North Korea at the express invitation of the Pyongyang authorities to cover the opening of a rare ruling party congress. They got within 200 meters of the venue, the April 25 Palace, and that was where they were stopped – on the other side of the road, under a steady drizzle that had been falling on the capital all morning. Instead of a rare glimpse of the country's highest-level political meeting for almost four decades, the media were then offered a tour of the March 26 Electric Cable Factory. North Korea issues reporting visas sparingly and escorts all journalists to make sure it sets the agenda and gets its point across. (Photo by Ed Jones/AFP Photo)
