Over the last decade Argentina has passed a series of progressive laws like gay marriage but abortion was off the table until now.
There have been passionate scenes outside Argentina’s congress after politicians narrowly voted in favour of legalising abortion.
The bill must now pass in the Senate, before it becomes law.
At the moment, abortion is only allowed in cases of rape or if the mother’s life is in danger.
