The U.N. Security Council is demanding "a complete, immediate and unconditional end to all fighting" between Sudan and South Sudan.

The council insists that both countries redeploy their forces 10 miles (16 kilometers) from a border that both recognized last year.

The council demands the withdrawal of South Sudan's military forces from the oil-rich town of Heglig that is claimed by Sudan and an end to Sudan's aerial bombing of South Sudan.

South Sudan's president said Thursday the nation will not withdraw its troops from the disputed border region.

The United States and Britain have also urged South Sudan to withdraw.
