The United States has expressed concern over an escalation in violence in Sudan's troubled Darfur region, after rebels captured a southern village.
A State Department spokesman said Wednesday both rebels and the government-backed militia have contributed to the increase in violence in Darfur. He said African Union cease-fire monitors are critical to bringing the situation under control.
Monday, the rebel Sudan Liberation Movement violated a cease-fire and launched a surprise attack on the town of Sheiria. The Sudanese government has threatened to retake the town.
Rebels have also recently accused the government-backed militia of incursions into rebel-held territory.
The violence comes during a sixth round of African Union-sponsored peace talks between Darfur rebel groups and the Sudanese government. AU officials said the renewed fighting could mar the talks and urged both sides to exercise restraint.
