Khartoum claims to have fought off the Jem attack, which aimed to topple the government. But it indefinitely extended a curfew, claiming that it is hunting down fleeing rebels.
Diplomats say that movements are restricted and the Egyptian news agency, Mena, says that the airport is closed.
The government accuses Chad's president of being behind the latest assault.
"The attempt by President Idriss Deby to destabilise Sudan has failed," senior ruling party official Kamal Obeid declared, while foreign Ministry official Ali Yousif claims to have evidence of communication between the rebels and Chad's government and its embassy in Khartoum.
In February, Chad accused Khartoum of helping rebels who stormed into its capital, Ndjamena, reaching as far as the gates of the presidential palace.
