Two Pakistani intelligence officials said the first suspected drone fired two missiles on a militants' vehicle in the Shawal area of South Waziristan, one of the seven districts of Pakistan's volatile tribal region bordering Afghanistan.

The second suspected drone strike targeted a hideout in the Wana area, also in South Waziristan.

Based on a count by the CNN Islamabad bureau, Monday's suspected drone strikes were the 37^th and 38^th this year, compared to 111 in all of 2010.

The intelligence officials asked not to be named because they were not authorized to speak to the media.
