Thousands of Iraqis marched on the U.S. Embassy in Baghdad to protest Senate sanctions against Iraq for its alleged use of chemical weapons against Kurdish separatists.

State-run Baghdad Radio said Iraqi and Kurdish demonstrators, which Arab news agencies estimated at tens of thousands, marched on the U.S. Embassy compound Sunday waving placards and chanting anti-American slogans.

The official Iraqi news agency INA said an Iraqi Kurdish girl left a petition signed by 25,000 people at the gates.

Gulf-based Western diplomats said the Iraqi government organized the demonstration to show its displeasure at what it saw as Washington's latest efforts to pressure Iraq into making concessions at the stalled peace talks.
