U.S. President Barack Obama says the United States is pledging nearly $300 million in humanitarian assistance to South Sudan which has seen months of ethnic fighting.
President Obama authorized the funding ahead of a donor's conference in Norway on Tuesday to raise money for the struggling country.
The White House says the assistance includes $50 million to support efforts by the United Nations to aid more than 300,000 refugees who have crossed into Ethiopia, Kenya, Sudan and Uganda.
It says more than one million additional people have been displaced inside South Sudan because of the fighting.
The violence in South Sudan broke out in December during a power dispute between President Salva Kiir and Riek Machar, his former deputy who was fired in July. The two men signed a cease-fire agreement earlier this month in Ethiopia.
