Abortion rights campaigners have rallied at the US Supreme Court to protest new restrictions on abortion passed in eight states.
Many of the restrictions are intended to draw legal challenges, which religious conservatives hope will lead the nation's top court to overturn a 1973 decision that established a woman's right to terminate her pregnancy.

US Senator Amy Klobuchar, one of the two dozen Democrats running for president, spoke at the rally.
"We are not going to allow them to move our country backward," she told the crowd through a megaphone.
Fellow candidate Senator Cory Booker urged the crowd to "wake up more men to join this fight".
The rally is one of scores scheduled for Tuesday around the country in response to laws passed recently by Republican state legislatures that amount to the tightest restrictions on abortion in the US in decades.
Alabama passed an outright ban last week, including for pregnancies resulting from rape or incest, unless the woman's life is in danger.
Other states, including Ohio and Georgia, have banned abortions absent a medical emergency after six weeks of pregnancy or after the fetus's heartbeat can be detected, which can occur before a woman even realises she is pregnant.
