A suspected U.S. drone fired five missiles at a militant hideout in North Waziristan, killing four suspected militants, two Pakistani intelligence officials told CNN Saturday. The attack was in the village of Mohammad Khel in the area of Data Khel.Such attacks are not unusual. Last week, at least 24 suspected militants were killed in two drone strikes in Pakistan's North Waziristan tribal region, Pakistani officials said. Based on a CNN count, there have been at least 34 drone strikes this year, including the most recent one. All of the drone strikes have targeted North Waziristan or its border with South Waziristan.
