US Army Spc. Natasha Schuette, 21, was pressured not to report being assaulted by her drill sergeant during basic training at Fort Jackson, South Carolina. Though she was hazed by her assailant’s fellow drill instructors, she refused to back down and Staff Sgt. Louis Corral is now serving four years in prison for assaulting her and four other female trainees. The US Army rewarded Natasha for her courage to report her assault and the Sexual Harassment/ Assault Response & Prevention office distributed a training video featuring her story. She is now stationed at Fort Bragg, North Carolina.

"My mother said that it was a typically quiet day, warm and windy. She and my father opened the window and they felt completely safe on the day of the explosion, the 26th of April 1986."

The world’s worst nuclear accident happened on 26 April 1986 at the Chernobyl nuclear power plant. Just 5 months after the disaster, a girl was born in Kiev just 100 km south from Chernobyl. The wind included a great amount of radioactive elements, and the girl became one of the victims of the tragedy. This series of pictures represent the last 30 years of the life of that invisible girl. All pictures taken on old Ukrainian color negative films, which were found in the city of Pripyat, located 5 km from the Chernobyl nuclear power plant.

Smoke rises from a building following reported shelling by Syrian government forces in Douma, Syria.

Douma, a rebel-held city in a suburb of the capital Damascus, lies in the opposition bastion area of Eastern Ghouta and has been subject to massive regime aerial bombardment. The area has also been under a crippling government siege for nearly two years as part of a regime attempt to break the rebel’s hold in the region. Douma and small rural towns in the Eastern Ghouta area were recorded as suffering from the highest number of fatalities since the start of the uprising against President Bashar al-Assad in March 2011, according to the Syrian Observatory of Human Rights. Government planes regularly bomb Douma and other small towns in Ghouta, which is an agricultural belt around the capital, leaving a constant trail of destruction and loss of lives.

At the end of September 2015, Russia launched air strikes in support of Syrian President Bashar al-Assad. The thunderous shelling in and around and the city has forced civilians from the town to join the growing number of more than four million Syrians fleeing the country since the Syrian conflict erupted in 2011.
