The second woman carrying a gene-edited foetus in China is now 12 to 14 weeks into her pregnancy, according to a US physician in close contact with the researcher who claimed to have created the world's first genetically-modified babies last year.

Chinese scientist He Jiankui shocked the scientific community after revealing that he had successfully altered the DNA of twin girls born in November to prevent them from contracting HIV.

State media reported on Monday that a preliminary investigation confirmed that a second woman became pregnant and that she will be put under medical observation, but no other details about her are known.
