(CNN) -- Chad pulled its troops out of Sudan on Sunday after destroying several rebel bases this month, a government official told CNN.
"We have no more troops in Sudan," said Chadian Information Minister Muhammad Hussein. The army withdrew after using ground troops and airstrikes to wipe out seven bases used to train Sudanese rebels, he added.
The Chadian government earlier this month claimed it had fought off rebel incursions, killing more than 280 rebels and capturing another 215.
"The army has worked to make sure there are no mercenaries in our territory," Hussein said Sunday. The goal was to "prevent the renewal of these attacks."
CNN could not independently confirm the claims. In the ongoing conflict between Chad and Sudan, both sides have accused the other of backing rebels to upend their governments.
On May 3, both countries signed an agreement in Doha, Qatar, to normalize relations and deny rebel groups their support.
But two days later, Chad accused Sudan of sending armed elements into eastern Chad, a charge which Khartoum denied, the United Nations said. That prompted U.N. Secretary-General Ban Ki-moon to warn against the destabilization of the region.
Chad is a landlocked country in northern Africa; it's south of Libya and west of Sudan.
