With more than 20,000 homicides so far, 2018 is on track to be Mexico's deadliest year on record. In a country where over 90% of crimes go unsolved, searching for truth and justice can make you a target. Civilians, journalists and politicians have been intimidated and killed, or have disappeared. Gianna Toboni investigates the roots of this spiraling murder rate and meets the people who refuse to be silenced.

After nearly four years of war in Yemen, at least 10,000 civilians have been killed, while millions more have fled their homes and now face famine and disease. The situation is so dire that the UN has described it as the world's worst humanitarian disaster. The crisis was created in large part by U.S. allies Saudi Arabia and the UAE, who have used U.S.-supplied weapons and planes to turn Yemen into a living hell. Ben Anderson returns to the country, where he obtains access to the various groups waging war for the Saudi- and Emirati-led coalition, and sees the devastating effects of chaotic fighting and indiscriminate bombing on civilians.
