WASHINGTON: Women seeking an abortion would be forced to have a procedure described by critics as ''state-sponsored rape'' under a controversial new law set to be passed by an American state this week.

To obtain a termination under the Republican plan, women in Virginia would first be made to have an ultrasound scan, which would allow them to see the foetus and to hear its heartbeat.

During the first three months of pregnancy - when 80 per cent of abortions occur - such an ultrasound must be carried out by vaginal probe. The plan is furiously opposed by women's rights groups and Democrats.

It is due to be signed this week by the state's Governor, Bob McDonnell, who is a high-profile ally of Republican presidential nominee candidate Mitt Romney.
