Islamabad, Pakistan (CNN) -- A suspected U.S. drone strike killed three alleged militants in Pakistan's tribal region Sunday, the second such strike in two days, intelligence officials told CNN.
Two intelligence officials said three missiles hit a suspected militant hideout in the Data Khel area of North Waziristan, one of seven districts in Pakistan's volatile tribal region bordering Afghanistan.
A strike in the same area Saturday also killed three suspected militants, the officials said.
The intelligence officials asked not to be named because they are not authorized to speak to the media.
Based on a count by CNN, Sunday's strike was the 64th drone strike this year and the 17th this month, the highest total for any month since the drone strikes began.
While the United States is the only country in the region of Pakistan and Afghanistan known to have the ability to launch missiles from drones -- which are controlled remotely -- U.S. officials normally do not comment on suspected drone strikes.
