'BREACH OF TRUST'

The security official said the US operation had left the Pakistani army and the ISI discredited in the eyes of the public."

"We are very angry about this breach of trust," the official said, speaking on condition of anonymity. "The space for cooperating with the Americans on military and intelligence operations has been shrunk because of this incident."

Compounding the pressure on the army, India for the first time directly accused a handful of serving Pakistani military officers of being involved with militancy. New Delhi's list of its 50 "most-wanted" criminals was handed to Islamabad in March, but its contents have only just been released.

India has long accused arch-rival Pakistan of harbouring militants such as those behind the 2008 Mumbai attacks that killed 166 people, who it says were supported by the ISI.

A day before talks with Pakistani President Asif Ali Zardari in Moscow, Russian President Dmitry Medvedev said bin Laden's killing would help Russia fight an Islamist insurgency in the south.

"The liquidation of terrorists, even on the level of ... bin Laden, has a direct relationship to the level of security on the territory of our state," Medvedev said in his first public comments on the al Qaeda leader's killing.

Russia's government faces a growing insurgency in mostly Muslim provinces of the North Caucasus after two wars since 1994 involving federal forces and separatist rebels in Chechnya.

In Beijing, Afghanistan's Foreign Minister Zalmai Rassoul said bin Laden's death may speed up reconciliation efforts between the Taliban and the Afghan government.
