Abortion-rights campaigners in the US gathered on Tuesday to protest restrictions on abortion passed by eight Republican-controlled states, including an outright ban in Alabama.

The new laws are attempting to draw legal challenges, which religious conservatives hope could overturn the 1973 case, Roe v Wade, which established the right for women in the US to terminate pregnancy.

Several Democratic presidential candidates joined the rallies, including Senator Cory Booker who urged a crowd outside the Supreme Court in Washington DC to “wake up more men to join this fight.”
