The US Supreme Court is currently considering whether to overturn a decades-old ruling that legalised abortion nationwide.
A draft decision, leaked late on Monday, showed a majority of justices are prepared to overturn the landmark 1973 Roe v Wade decision that protects abortion rights.
Such a move would dramatically reduce reproductive rights in the US and mean access to abortion services is no longer a constitutional right. Each state would have the right to outlaw the procedure.
According to the Center for Reproductive Rights, 90 million women of reproductive age worldwide – or 5% – live in countries where abortion is completely illegal.
Here, Yahoo News UK looks at the laws in other nations where access to abortion is permitted only under extreme circumstances, or banned altogether.
