Islamabad, Pakistan (CNN) -- Two suspected U.S. drone strikes in Pakistan's tribal region killed 15 people Wednesday, two intelligence officials said.
Ten militants were killed when a drone fired four missiles on two militants' hideouts in the area of Wana in South Waziristan, one of the seven districts of Pakistan's volatile tribal region bordering Afghanistan.
Five militants were killed in another strike in the Miranshah area of North Waziristan, widely believed to be a safe haven for the Haqqani network, a pro-Taliban militant group accused of fueling the insurgency across the border in Afghanistan.
Based on a count by the CNN Islamabad bureau, Wednesday's suspected drone strikes were the 33rd and 34th this year, compared with 111 in all of 2010.
The intelligence officials asked not to be named because they were not authorized to speak to the media.
