US drone attacks are antagonizing people in the tribal areas and undermining Pakistan's efforts to seek broader support for the efforts against terrorism, Foreign Office spokesman Mohammad Sadiq said Friday. Responding to questions at a media briefing here at the Foreign Office, the spokesman said Pakistan has repeatedly expressed its position on the US drone attacks inside its territory, calling them unproductive as they strengthen the militants instead of helping the war on terror. "We condemn these attacks. These are most unfortunate and constitute a gross violation of our sovereignty and territory," he said . "We have raised the issue of attacks with the US authorities at every level and underscored that these attacks should be stopped immediately."
