The 2018 Nobel Peace Prize has been awarded to Dr. Denis Mukwege, a Congolese gynecologist, and Nadia Murad, a Yazidi survivor of rape and captivity by ISIS, for their contributions toward combating wartime sexual assault.

The prize was announced by the Norwegian Nobel Committee in Oslo, Norway, on Friday morning. The committee praised the winners for being symbols in the fight to end the use of sexual violence as a weapon of war and armed conflict.

Peru's Supreme Court overturned a medical pardon for the polarizing former President Alberto Fujimori, saying the 80-year-old must return to jail to serve his sentence for crimes against humanity, which cannot be pardoned under Peruvian and international law.

On June 5, 1968, hotel busboy Juan Romero raced to congratulate Sen. Robert Kennedy moments after his victory in the California presidential primary. He had met the candidate the day before, bringing him room service at the Ambassador Hotel in Los Angeles.

As Kennedy briefly paused to shake the hand of the 17-year-old, a man named Sirhan Sirhan gunned down Kennedy in front of Romero. A remarkable photograph captured the scene: young Romero, an immigrant from Mexico, cradling the glassy-eyed Kennedy, member of an American political dynasty.

Capitol Police have arrested a man accused of publishing to the Internet restricted personal information about South Carolina Republican Sen. Lindsey Graham.

The FBI has arrested a man in Utah who authorities believe mailed letters to the Pentagon containing castor seeds — a key ingredient in the highly toxic substance ricin.

William Clyde Allen III of Logan, Utah, was arrested by agents with the Salt Lake City Division of the FBI.

Two envelopes mailed to the Pentagon earlier this week tested positive in a screening center for a hazardous substance. After conducting further tests, the FBI determined the envelopes contained castor seeds.
