CHICAGO (MCT) — Six people were arrested at Holy Name Cathedral Sunday after disrupting an Easter Mass to protest the Iraq war.

The group, whose female and male members identified themselves as Catholic Schoolgirls Against the War, stood up at the beginning of Cardinal Francis George's homily and shouted their opposition to the conflict, which marked its fifth anniversary last week. As security guards and ushers tried to remove them from the service, the demonstrators squirted fake blood upon themselves and parishioners dressed in their Easter finery.

The red substance, which one protester later described as "stage blood," initially drew gasps and a few terrified yelps from the 600 worshipers at the mass. The shock, however, quickly transformed into anger as people booed the six as they were escorted from the parish auditorium where the holiday service was taking place.

The protesters were all charged with felony criminal damage to property and two counts of simple battery for squirting the blood around the auditorium and onto worshipers clothes.
