ISLAMABAD: The United States did not inform Pakistan about a missile strike on militants hours after the top US military officer said the United States would respect Pakistan’s sovereignty, Pakistan’s foreign minister said.

The United States, frustrated by an intensifying Taleban insurgency in Afghanistan, has stepped up attacks on militants in Pakistan with six missile attacks by pilotless drones and a helicopter-borne ground assault this month.

US officials say Taleban and Al-Qaeda-linked fighters use ethnic Pashtun tribal regions on the Pakistani side of the border as a springboard for attacks into Afghanistan. But the US attacks have infuriated many in Pakistan, which is also battling Al-Qaeda and Taleban militants, and the army has vowed to stand up to aggression across the border.

The latest missile strike, on the Pakistani side of the Afghan border on Wednesday evening, killed five militants, and was the result of better US-Pakistani intelligence sharing, a senior Pakistani official with knowledge of the operation told Reuters earlier.

The official, who spoke on condition of anonymity because of the sensitivity of the subject, said Pakistani intelligence had been notified of the attack by the United States, but did not say whether it was before or after the missiles struck. “There was intimation at the intelligence level,” he said.

But Foreign Minister Shah Mehmood Qureshi told a briefing yesterday the United States had not warned Pakistan about the attack in advance. “We were not informed,” Qureshi said.

Hours before the strike, Adm. Mike Mullen, chairman of the US Joint Chiefs of Staff, assured army commander Gen. Ashfaq Kayani and Prime Minister Yousaf Raza Gilani that the United States would respect Pakistan’s sovereignty.

“If having said that, there was an attack later in the night, that means there is some sort of institutional disconnect on their side,” Qureshi said. Such attacks would not improve the situation and were unproductive, he said.
