Pabla Maghar Singh, 38, said the mother of his newborn children has lived in Italy for 15 years, but returned to her native country for fertility treatments after a number of attempts at becoming pregnant in Italy failed, ANSA reported Thursday.

Singh said the four newborn boys, named Manav, Manmeet, Roshan and Radveer, were born prematurely but were progressing well in an incubator at a Mantua hospital.

''We are happy, we wanted these children so much,'' the father said.
