Both countries have been at odds with each other for the past five years as they have regularly accused each other of fomenting cross-border attacks.
In another development, EU foreign policy chief Javier Solana defended the European force, or EUFOR, on the ground in Chad Tuesday after Chadian President Idriss Deby accused the force of favouring Chadian rebels.
Rebels attacked an area near Goz Beida Saturday, and Irish EUFOR soldiers returned fire, confirmed Christina Gallach, Solana's spokesperson in Brussels. No casualties were reported.

Rebels attacked Biltine on Monday, some 750 kilometres east of the Chadian capital. They have vowed to attack Njamena again after a failed coup attempt in February.
