Dutch campaigners have used a drone to fly abortion pills into Poland, reports BBC.

The group, Women on Waves, flew the aircraft from Germany to highlight Poland's restrictive laws against terminating pregnancies.

Abortion was legal in Poland in the Communist era, but outlawed in most cases in 1993.

It is only permitted in cases of rape or incest, in cases of irreversible foetal malformation, or if the mother's life is at risk.

Women on Waves argues that Poland's restrictive laws simply drive women into undertaking risky back-street abortions, and that even women who are legally entitled to end their pregnancies are sometimes refused treatment by doctors and hospitals.
