The Clinton Administration disclosed new intelligence information today in an effort to persuade its allies not to lift economic sanctions against Iraq, asserting that Baghdad still uses terrorism to kill opponents abroad and had developed vast stocks of germ warfare agents.

In a hearing before a Senate Foreign Relations subcommittee, Madeleine K. Albright, the chief United States delegate to the United Nations, took an unyielding attitude toward easing the sanctions, a move that France and Russia hope the Security Council will approve next month.

Sounding like a prosecutor, Ms. Albright ticked off point by point how Iraq continues to flout United Nations resolutions with which it is supposed to comply in order for sanctions to be lifted.

Iraq, she said, has failed to dismantle its weapons of mass destruction, failed to return property stolen from Kuwait, failed to stop supporting terrorism and failed to stop repressing the Kurds and minority groups.
