Mexico's Supreme Court has ruled that criminal penalties for terminating pregnancies are unconstitutional.
Abortion is currently severely restricted in all but four of the country's states.
Supreme Court Justice Luis Maria Aguilar described the move as a "historic step for the rights of women".
On Tuesday, the court ordered the state of Coahuila to remove sanctions for abortion from its criminal code.
The decision could pave the way for the decriminalisation of abortions across the country.
Currently, abortion is only legal in a handful of states, except in cases of rape or where the mother's life is in danger.
