LONDON (Reuters) – An army of religious sisters who rescue victims of human trafficking by posing as prostitutes to infiltrate brothels and buying children being sold into slavery, is expanding to 140 countries, its chairman said on Wednesday.

John Studzinski, an investment banker and philanthropist who chairs Talitha Kum, said the network of 1,100 sisters currently operates in about 80 countries but the demand for efforts to combat trafficking and slavery was rising globally. MORE
