Women stage global fast to pressure UK over Nazanin Zagari-Ratcliffe

Participants in women's fasting relay will demand Boris Johnson repay 400m to Iran for 1970s arms deal

Women around the world will take turns to fast for 24 hours in an attempt to put pressure on the UK government to secure the freedom of Nazanin Zaghari-Ratcliffe from detention in Iran.

The campaign by FiLiA, a female-led volunteer organisation working for the liberation of women, follows the 21-day hunger strike Nazanin's husband, Richard Ratcliffe, mounted outside the Foreign Office in London until mid-November.
