"It is not enough to move terrorist camps from Pakistani-occupied-Kashmir to the Punjab: the camps, and the groups, must be dismantled, the terrorist financial networks must be eliminated and the terrorists must be arrested and prosecuted, not merely put under house arrest or other informal detention," they said in a joint letter to the President, copies of which were made available to media in Washington on Thursday night.

The Congressmen said, "It is also time, however, to dismantle the terrorist networks that threaten Pakistan's internal stability and engage in terrorism across the Line of Control in Kashmir."

Pakistan can no longer afford its dalliance with groups like Jaish-e-Mohammed and Lashkar-e-Taiba, they said.

Signatories to the joint letter were Frank Pallone, Jim McDermott, Gary Ackerman, Joseph Crowley, Tom Lantos, Harold Ford, Melvin Watt, Robert Wexler, Barbara Lee, Adams Schiff, Howard Berman, Edward Markey, Ellen Tauscher, Robert Matsui and Shefley Berkley (all Democrats) and Ileana Ros-Lehtinen (Republican).

Bush had announced a five-year, $3 billion assistance package for Pakistan during Musharraf's visit to the US in June.
