A suspected U.S. drone strike killed 20 people in North Waziristan , a region along the Pakistan-Afghanistan border , a Pakistani intelligence official told CNN Friday . An officer from the political administration told CNN that six missiles struck a compound in Datakhel , an administrative division of North Waziristan . The region is known to be a hotbed for militancy and widely believed to be under little government control . Both officials requested not to be identified because they are not allowed to disclose information to the media . A military officer who requested anonimity for the same reason , told CNN that two drones were in the area , but only one of them fired . In the incident , which occurred shortly after 10 p.m. , two missiles struck the compound in the residential area followed by another four missiles that were fired 10 minutes later , the officer said . The death toll rose from nine to 20 as people who had gathered at the site after the first strike were hit in the second , the officer said . It was not clear if any of the dead were civilians . U.S. Secretary of State Hillary Clinton apologized this week for a coalition attack last November in which NATO fighter jets attacked a Pakistani checkpoint near the Afghanistan border , killing 24 Pakistani soldiers . U.S.-Pakistan relations soured after the incident , which led Pakistan to close supply routes for NATO trucks carrying supplies to Afghanistan . After the apology , Pakistani leaders reopened the routes through Pakistan 's western border . Islamist political parties expressed outrage at their reopening , accusing the government selling out to U.S. demands and disregarding the will of its own parliament . Pakistan 's parliamentary committee on national security passed a resolution in April that set the cessation of drone strikes as a condition for the reopening of supply routes to Afghanistan . Pakistan will continue to press the U.S. administration to stop drone attacks , Qamar Zaman Kaira , Pakistan 's minister for information and broadcasting , said after the Clinton apology . Pakistani government officials have been angered by suspected U.S. drone airstrikes in the country that have left many dead . The U.S. military routinely offers no comment on reported drone strikes .
The strikes were the first since Pakistan agreed to reopen routes . Islamist parties accuse the government of selling out to U.S. demands . The region is a hotbed for militancy .
