ISLAMABAD (Reuters) Pakistan opposes expanded US drone attacks against militants on its tribal areas, as well as any strikes on Balochistan, where Washington believes Afghan Taliban leaders are hiding, the foreign ministry said on Friday. Missile strikes from pilotless drone aircraft have created fierce anti-American sentiment in Pakistan, a strategic ally Washington wants to crack down harder on Taliban fighters operating along the porous border with Afghanistan. The White House has authorised the expansion of the CIAs drone programme in Pakistan to complement President Barack Obamas plans to send 30,000 more troops to Afghanistan, the New York Times reported, citing unnamed officials. It said that for the first time, US officials are talking with Islamabad about the possibility of hitting Balochistan. Foreign Ministry spokesman Abdul Basit said there were limits to Pakistani cooperation, and the drone attacks were counterproductive. This has never been part of our discussions. There are clear red-lines as far as were concerned, he said when asked if there were any talks between Washington and Islamabad on expansion of drone attacks to Balochistan. We have clearly conveyed our red-lines to them. The CIA-operated drones have already been increasingly used near the Afghan border. Nearly 50 drone air strikes in northwestern border regions this year have killed about 415 people, including many foreign militants, according to officials and residents. But it is not just a rise in drone attacks, but the widening of the war geographically that worries Pakistanis.
