He said that drone strikes complicated the anti-terror drive. “Such attacks fuel anti US sentiments and are killing civilians.”  The president said that US guidelines over drone attacks in Pakistan needed to be reviewed.  Stressing on enhanced intelligence sharing to combat militancy in tribal areas, he said ‘our forces are well equipped and competent enough to handle terrorists’. Zardari said that due to huge sacrifices rendered by armed forces ‘we have broken the back of terrorists’.  Sources added that the president assured the envoy that the government was committed to holding free and fair elections on time.  He hoped that Olsen’s tenure as ambassador would serve to burnish Pak-US relations.
