WASHINGTON (Reuters) - Pakistan's top military spy agency has arrested five CIA informants who fed information to U.S. intelligence before the raid last month which killed Osama bin Laden, The New York Times reported on Wednesday.

One of the detainees was reported to be a Pakistani Army major whom officials said copied license plates of cars visiting the al Qaeda leader's compound 30 miles northwest of Islamabad.

The fate of the CIA informants arrested in Pakistan was unclear, the newspaper reported, citing American officials.

Outgoing CIA Director Leon Panetta raised the issue of the informants' detention during a trip to Islamabad last week where he met Pakistani military and intelligence officers, the newspaper said.
