Nobel Peace Laureates sign statement against war and nuclear weapons

"As Nobel Peace Prize Laureates...we call on all our fellow citizens of the world to join us in protecting our planet, home for all of us, from those who threaten to destroy it. The invasion of Ukraine has created a humanitarian disaster for its people. The entire world is facing the greatest threat in history: a large-scale nuclear war, capable of destroying our civilization and causing vast ecological damage across the Earth."

IPPNW Responds to Crisis in Ukraine

IPPNW’s global federation of health professionals and our partners have worked diligently to promote peace and warn decision-makers and the general public of the humanitarian disaster that would follow any use of nuclear weapons.

The week of 18 February, over 150 medical students in six countries carried IPPNW’s mission to their local communities via regional bike tours. Despite the physical distance between the chapters, all were brought together with one unifying message: the abolition of nuclear weapons is a public health imperative.
