(Updates with five arrested, quote from protester, charges)

WASHINGTON, Oct 24 (Reuters) - An anti-war protester waved blood-colored hands in U.S. Secretary of State Condoleezza Rice's face at a congressional hearing on Wednesday and shouted "war criminal!", but was pushed away and detained by police.

"The blood of millions of Iraqis is on your hands!" yelled the protester, Desiree Anita Ali-Fairooz of the Code Pink organization which often disrupts hearings on Capitol Hill with protests against the Iraq war.

Rice, an architect of President George W. Bush's Iraq policy, appeared unfazed by the incident, which occurred when she entered a House of Representatives meeting room to testify at a hearing on U.S. Middle East policy.

"Out!," shouted the chairman of the Foreign Relations committee, Rep. Tom Lantos, as plain-clothes security men and police hustled the woman away. The California Democrat also ordered the removal of several other Code Pink activists.

Capitol Police said later five people were arrested, including Ali-Fairooz, who was charged with disorderly conduct and assault on a police officer.

She was also charged with defacing government property for smearing the red paint from her hands on the hallway wall outside the hearing room. The other four protesters faced disorderly conduct charges.
