The central African nation of Chad has asked the African Union to condemn Sudan for its alleged support of Chadian rebels.
Chad's president, Idriss Deby, made the appeal Tuesday during a meeting with Nigerian President and AU chairman Olesgun Obasanjo at his residence outside Lagos.
Chad says Sudan harbors and supports the anti-Deby rebels who attacked the eastern Chadian town of Adre earlier this month. Sudan has denied the accusations.
Earlier, President Deby accused Sudan of planning another attack, saying the Sudanese military has deployed 50 armored vehicles to the town of Geneina near the Chad-Sudan border.
He said Sudan's actions could destabilize other states in the region, including the Central African Republic.
The African Union has sent delegations to both countries' capitals in an effort to defuse the rising tensions.Some information for this report provided by AFP and Reuters.
