(AP) — Thousands of Poles took part in street demonstrations on Sunday to protest a possible tightening of the country’s abortion law, already one of the most restrictive in Europe.

The rallies in Warsaw and other cities were held under the slogan “No to the torture of women” and came as the influential Roman Catholic Church launched a campaign for a total ban on abortion, something supported by Prime Minister Beata Szydlo and ruling party leader Jaroslaw Kaczynski.

Abortion is currently illegal in Poland in most cases but there are exceptions if the pregnancy poses a threat to the woman’s health or life, if it results from a crime like incest or rape or if the fetus is damaged.

Protesters say a total ban would lead to women dying or force them to travel to other countries for abortions. In Warsaw they strung up coat hangers, a symbol of primitive underground abortions.

The current abortion law dates to 1993 and was a compromise between the country’s liberal and Catholic circles.

Priests across Poland read out a letter from bishops in churches Sunday calling for lawmakers to initiate legislation that would impose the total ban on abortion. The letter argued there can be no compromise on the matter, citing the Biblical precept “Thou shalt not kill.”

The ruling Law and Justice party has a majority in parliament and would be in a position to change the abortion law if all of its lawmakers support that change. It’s not yet clear if most would follow party leader Kaczynski in supporting the ban.

The party won elections last year promising deep changes to the country, including a return to traditional Catholic values.
