South Sudan’s government forces are responsible for a majority of the brutal killings and attacks on civilians, according to separate reports by the United Nations and Amnesty International.

The UN report, released today, called on government officials to take responsibility for their crimes. South Sudan’s civil war began in 2013 after a failed coup by soldiers loyal to the dismissed vice president, Riek Machar. In an effort to end the conflict, Machar has been reinstated to his position, but the extrajudicial killings continue.

The retirement home housed about 80 residents and is run by Missionaries of Charity, the religious order established by Mother Theresa in 1950.

French forces in Mali killed a Spanish al-Qaeda commander earlier this week, striking a blow to the extremists terrorizing North Africa. But experts warn military victories alone will not be enough to defeat the ideologically driven group.
