According to a statement by the Foreign Office, Special Assistant to Prime Minister on Foreign Affairs Tariq Fatemi pointed out to the US envoy that the drone strike was a "violation of Pakistan's sovereignty and a breach of the UN's Charter that guarantees the inviolability of the territorial integrity of its member states."
Fatemi also emphasised that "such actions could adversely impact the ongoing efforts by the Quadrilateral Coordination Group (QCG) for facilitating peace talks between the Afghan Government and the Taliban."
Mansour, believed to be in his 50s, was killed when a US drone fired on his vehicle in the southwestern Pakistani province of Baluchistan. He had emerged as the successor to Taliban founder Mullah Mohammad Omar, whose 2013 death was only revealed last summer.
