BEIJING (Reuters/AFP) - Chinas top state newspaper on Tuesday accused the United States of flouting international law and fanning terrorism after a Nato attack killed 24 Pakistani soldiers, and it warned that the Islamabads grip on security could be dangerously weakened. The strongly-worded editorial in the Peoples Daily - mouthpiece of Chinas ruling Communist party - came after Beijing said it was deeply shocked by the strikes, which have exacerbated tensions between Islamabad and Washington. The United States and Nato have violated international law and international norms, the paper said in an editorial condemning the attacks. This shows... that at crucial moments, the United States will not show the slightest hesitation to violate the sovereignty of another nation to ensure its 'absolute security. The use of such cross-border tactics will only incite terrorist sentiment, the editorial added. The risk in fighting terror this way is that it will ignite latent sympathy and support for terrorism, as well as hurting many innocent people and damaging international law, said the editorial. The soil nurturing terrorism will become even more fertile, and the space for terrorism to spread even broader, it said. The Peoples Daily commentary said the killings of the soldiers could inflict lasting damage. Islamabads grip on domestic security will also be weakened, it said. This will not only work against the war on terror, it could also leave the risk of long-term turmoil. Pakistan has reacted furiously to what it called an unprovoked strike, worsening US-Pakistani relations already in crisis after the killing in May of Osama bin Laden north of Islamabad by US special forces. Chinese Foreign Minister Yang Jiechi spoke to his Pakistani counterpart Hina Rabbani Khar on Monday and expressed shock over the attacks, a government statement said. All nations of the world and international organisations should fully respect Pakistans independence, sovereignty and territorial integrity, Yang said, according to the statement. The paper slammed the US for, what it called, the United States flouted international law and fanned terrorism by launching attack which killed 24 Pakistani soldiers.
