WARSAW, Poland — Thousands of Poles, many dressed in black, rallied Saturday in front of parliament in Warsaw to protest a proposed bill that would impose a complete ban on abortion.

Speakers at the so-called “Black Protest” said a total ban on abortion, including for victims of rape or women whose lives are endangered by a pregnancy, would be “barbaric.” Poland already has one of Europe’s most restrictive abortion laws.

Organizers chose black as a symbol of mourning for the loss of reproductive rights that they say women could suffer if the law passes. In rallying speeches, they said they want as few abortions as possible in Poland, but that this goal should be achieved with better sex education in schools and easier access to birth control.

“We will not allow our hospitals to be turned into torture chambers and our doctors into prison guards,” Agnieszka Dziemianowicz-Bak, a member of the left-wing Together party, told the crowd.
