QUETTA The NATO fighter planes reportedly violated Pakistans airspace for almost thirty minutes in the Zhob district on Wednesday. According to sources, NATO jet planes were seen flying over the bordering area of Zhob district, some 300 kilometres away from Quetta, on Pak-Afghan border. The planes whose number could not be ascertained remained in Pakistans airspace for almost 30 minuets and later returned to Afghanistan. The movement of warplanes created panic among the residents of these localities who thought that these planes would make air strikes in the area. The sources informed that after violation of Pakistans airspace, the security in border areas has further been tightened and authorities concerned have been informed about this violation. The official sources on the condition of anonymity have confirmed the report. However, the DG ISPR Gen Athar Abbas, when contacted by TheNation, said that he had absolutely no information about this.
