South Sudan's Vice President Riek Machar has been charged with murder, treason, and crimes against humanity in connection with an attack on a military base that killed over 250 soldiers. This legal action comes as a fragile power-sharing agreement between President Salva Kiir and Machar continues to unravel in the world's youngest country.

• Over 250 soldiers died in the attack on a military base in Nasir County, Upper Nile State, between March 3 and 7.
• Justice Minister Joseph Geng Akech announced the charges against Machar and 20 others, including murder, conspiracy, terrorism, and destruction of public property.
• A militia from Machar's Nuer community, known as the White Army, is accused of overrunning the military base, leading to the casualties and accusations of gross violations of the Geneva Conventions.
