The United Nations High Commissioner for Human Rights says the security situation in Central African Republic is deteriorating three weeks after the government was overthrown.

Navi Pillay on Tuesday expressed concern about "a wide range of alleged grave violations" including rape, torture, kidnappings and targeted killings.

Pillay said at least 119 people have been killed since President Francois Bozize was ousted from power on March 24 by rebels from an alliance known as Seleka.

The U.N. also has heard of at least 19 cases of sexual violence in Berberati, and several other reported attacks in the capital of Bangui.

Rebel leader Michel Djotodia is now president of a transitional council that plans for elections within 18 months, though critics say his government lacks control over its fighters in the streets.
