The United States again appears to be relying on missile strikes by unmanned aircraft to target militants in Pakistan’s tribal belt. According to the Associated Press, intelligence officials say suspected U.S. aircraft launched four missile strikes today at a house and two vehicles in northwestern Pakistan near the Afghan border. They say the victims included three foreigners. The attacks took place in an area dominated by militants who often attack U.S. and other foreign troops in Afghanistan. The U.S. is now suspected of carrying out 14 missile strikes in the region this month.
