Human Rights Watch is urging the United States to use its Security Council presidency to create a new U.N. force in Sudan's troubled Darfur region.
The New York-based group says such a mission should have a strong mandate to protect civilians.
The rights group says the African Union troops now in Darfur have acted with great resolve and courage, but lack manpower and resources. It says the deteriorating situation in Darfur demands a major new international effort to save lives there.
Human Rights Watch says the United States should use its presidency of the Security Council in February to jump-start this effort.
Violence against civilians in Darfur has surged in the last three months. Human Rights Watch blames militias sponsored by Sudan's government.
