* Sudan's Mukhabarat, its version of the CIA, has detained Al Qaeda suspects for interrogation by U.S. agents.
* The Sudanese intelligence agency has seized and turned over to the FBI evidence recovered in raids on suspected terrorists' homes, including fake passports.
* Sudan has expelled extremists, putting them into the hands of Arab intelligence agencies working closely with the CIA.
* The regime is credited with foiling attacks against American targets by, among other things, detaining foreign militants moving through Sudan on their way to join forces with Iraqi insurgents.
Sudan has "given us specific information that is ... important, functional and current," said a senior State Department official who agreed to discuss intelligence matters on condition of anonymity. The official acknowledged that the Mukhabarat could become a "top tier" partner of the CIA.
"Their competence level as a service is very high," the official said. "You can't survive in that part of the world without a good intelligence service, and they are in a position to provide significant help."
From Khartoum the view is markedly upbeat.
"American intelligence considers us to be a friend," said Maj. Gen. Yahia Hussein Babiker, a senior official in Sudan's government.
During an interview at the presidential palace, Babiker said Sudan had achieved "a complete normalization of our relations with the CIA."
Intelligence chief Maj. Gen. Salah Abdallah Gosh, who otherwise declined comment for this article, told The Times: "We have a strong partnership with the CIA. The information we have provided has been very useful to the United States."
The paradox of a U.S.-Sudanese intelligence partnership is personified by Gosh.
