Pakistan has agreed to allow the CIA to send a forensics team to examine the compound where Osama bin Laden was killed, giving the agency permission to use sophisticated equipment in a search for al-Qaeda materials that may have been hidden inside walls or buried at the site, U.S. officials said.
The arrangement would allow the CIA for the first time to enter a complex that it had previously scrutinized only from a distance, using satellites, stealth drones and spies operating from a nearby safe house that was shuttered when bin Laden was killed.
U.S. officials said that a CIA team is expected to arrive at the compound in Abbottabad, Pakistan, within days and that the objective is to scrub the site for items that were not recovered by American commandos during the raid early this month or by Pakistani security forces who secured the facility afterward.
“The assault team was there for only 40 minutes,” a U.S. official said. The aim is to return to the site “to do another, more thorough look.” The official, like others interviewed, spoke on the condition of anonymity to discuss intelligence matters.
