Sources: U.S. grills 'hostile' bin Laden wives, via Pakistan officials

(CNN) - Three of Osama bin Laden's wives have been interrogated by U.S. intelligence officers under the supervision of Pakistani's intelligence service, according to sources in both governments.

The women - who were all interviewed together - were "hostile" toward the Americans, according to a senior Pakistani government official with direct knowledge of the post-bin Laden investigation and two senior U.S. officials with direct knowledge of the matter. The eldest of the three wives spoke for the group.

Members of Pakistan's Inter-Services Intelligence were in the room along with the U.S. intelligence officers, the officials said. The Americans had wanted to question the wives separately to figure out inconsistencies in their stories.

All three officials said that the interrogation didn't yield much new information, while adding that it was early in the process.

Both the senior Pakistani and senior U.S. officials said that - despite some well-publicized strains - there is an ongoing exchange of intelligence between the two countries.

The story was first reported Thursday night on CNN's "Anderson Cooper: 360."
