Moscow: Violation of national sovereignty during anti-terrorist operations was 'impermissible' Russia has said in the backdrop of killing of 24 Pakistani soldiers in a cross-border NATO attack.

Foreign Minister Sergei Lavrov on Monday called his Pakistani counterpart Hina Rabbani Khar to express Moscow's condolences at the loss of life in the cross-border air strike.

Lavrov backed Islamabad's stance over last Saturday's NATO air strikes on its two border post, in which 24 Pakistani soldiers were killed.

"The Russian Foreign Minister expressed understanding at the stance taken by the Pakistani leadership and underscored that the violation of national sovereignty was impermissible, including in planning and carrying out counterterrorism operations," Russian Foreign Ministry said in a release posted on its website.

However, Moscow had welcomed the elimination of terror -supremo Osama bin Laden by the US commandos in Pakistan's Abbottabad in May last, when Islamabad was kept in dark.

During his telephonic conversation with Khar, Lavrov also called for a thorough probe by the high command of NATO-ISAF in Afghanistan.

Meanwhile, the Russian media has noted that the closure of US-led NATO force's supply root by Pakistan was in favour of Moscow.

Kommersant business and political daily noted that NATO is left with alternate supply root through Russia and presumed that Moscow could use it as an instrument to influence US-led NATO's stand on deploying missile shield in Europe, seen as the post-Communist nation as a mortal threat to its nuclear deterrence inherited from the Soviet Union.
