Tens of thousands of people have been taking part in rallies across the United States demanding continued access to abortion.

In Washington, thousands marched on the Supreme Court, which will decide the future of abortion rights in the United States over the next few months.

Pro-choice supporters fear a 1973 case, Roe v Wade, which legalised abortion in the US could be overturned by the conservative -controlled Supreme Court.

It comes after the state of Texas introduced a law last month banning terminations after six weeks, a point when many women don't know they are pregnant.

The law also gives any individual the right to sue doctors who perform an abortion past the six-week point.

Supporters say the law aims to protect the unborn and the issue has become one of the most polarizing in U.S. society.

Opponents cite religious beliefs about the sanctity of life, while abortion rights activists say that restrictions rob women of control over their bodies and futures.

Last week, the Biden administration urged a federal judge to block the Texas law. In September, a federal appeals court blocked a similar strict abortion law in Tennessee.
