ISLAMABAD, July 23 (RIA Novosti) - Pakistan said Monday no nation would be permitted to conduct military operations on its territory in response to remarks made by senior U.S. officials that such an option is being contemplated in Washington.

"We have made it very clear that any attack on Pakistani territory will be considered unacceptable," Tasnim Aslam, the spokesman for the Pakistani Foreign Ministry, told an Islamabad news conference.

"Any counterterrorism measures in Pakistan will be only made by our own security forces," she said.

The statement came in the wake of remarks Sunday by U.S. President's homeland security adviser Frances Fragos Townsend, National Intelligence Director Mike McConnell, and Senate Majority Leader Harry Reid, who said Washington should "find these evil people and go get them [wherever they are]," and "use any instrument at our disposal" to hunt Osama bin Laden, the alleged mastermind behind the 9/11 attacks in New York and Washington.

Bin Laden is thought to have moved to a tribal area on the border between Pakistan and Afghanistan after the Taliban, a radical Islamist group that ruled Afghanistan for five years, were defeated by allied Western forces.

Earlier this month, U.S. Congress overwhelmingly approved a bill to double the bounty for the capture or information leading to the arrest of Osama bin Laden to $50 million.
