Islamabad, Pakistan (CNN) -- Three suspected U.S. drone strikes killed 13 people Wednesday in Pakistan's tribal region, two intelligence officials told CNN.
All three incidents occurred in North Waziristan, one of the seven tribal districts bordering Afghanistan.
Five suspected militants died in Data Khel when a drone fired two missiles at a vehicle.
A drone in the Mir Ali area fired three missiles at a vehicle and killed four suspected militants.
And, a vehicle was targeted earlier in Miran Shah and four suspected militants were killed there as well.
Based on a count by the CNN Islamabad bureau, Wednesday's third suspected drone strike was the 87th this year compared to 52 in all of 2009.
The officials asked that they not be named because they were not authorized to talk to the media.
