ISLAMABAD The Government of Pakistan has strongly condemned and protested to ISAF/NATO against the two incidents of aerial engagements from the Afghan side into Pakistani territory by the international forces helicopters. These incidents are a clear violation and a breach of the UN mandate under which ISAF operates, said a statement issued by the Foreign Office on Monday. According to the statement, Pakistan has made it clear to NATO that UNs mandate terminates/finishes at the Afghan border and there are no agreed hot pursuit rules, so, such violations are unacceptable. ISAF/NATO has been asked not to participate in any military action that violates the UN mandate and infringes upon Pakistans sovereignty. In the absence of immediate corrective measures, Pakistan will be constrained to consider response options, a spokesperson of Foreign Office said. He further said that Pakistan has always emphasised the need for a coordinated and joint action against the forces inimical to regional and global peace. Pakistan has boldly and at a great cost countered terrorists. Element of trust followed by capacity enhancement of Pakistans Armed Forces was stressed. The demarche has been relayed to the NATO headquarters in Brussels, Basit said. It is important to mention here that NATO helicopters based in Afghanistan had carried out two air strikes inside Pakistan killing more than 30 tribesmen. NATO is said to have justified the strikes based on the right of self-defence, however, the Foreign office spokesperson condemned the attacks and said that Pakistan has always emphasised the need for a coordinated and joint action against forces inimical to regional and global peace.
