The first pair of drone-fired missiles hit a vehicle and a compound near Wana, the main town in South

because they were not authorized to talk to the media.
The victims were believed to be allied with Maulvi Nazir, a prominent cut-thoat commander in the area, according to the officials.
South Wazoo was the main sanctuary for the Pak Taliban until the army launched a large ground offensive in 2009. But bully boyz continue to infest the area and often carry out attacks against Pak soldiers.
Later, four missiles hit a vehicle in North Wazoo, considered a major cut-thoat sanctuary, killing five, the officials said.
The US does not publicly discuss drone strikes in Pakistain, but officials have said privately that they have killed several senior al-Qaeda and Taliban capos. More than 200 attacks have taken place since 2009.
The frequency of attacks dropped in earlier in the year, but have since resumed their normal pace.
The uptick follows the U.S. raid that killed the late Osama bin Laden

in Pakistain on May 2. That operation angered the Mighty Pak Army and parliament, which demanded an end to the strikes.
Pakistain's army has been known to cooperate with some of the attacks in the past, but it is unclear whether it still does so.
