Media freedom group Reporters Without Borders said Tuesday that the U.S. made it into the top five deadliest countries for journalists this year for the first time, with six dying, including four who were among five people killed by a gunman who opened fire in the offices of Maryland newspaper Capital Gazette on June 28. The shooting was the deadliest single attack on the media in recent U.S. history. A sales associate was also killed. The man had threatened the newspaper after losing a defamation lawsuit. Another two died while covering extreme weather.
