Iokem Sigalas, chief director of the Ippokratio Hospital in Greece's main northern city of Thessaloniki, said on Saturday the twins were born by caesarean section, now weighed five kilograms and had steadily put on weight since their birth at the hospital.
"They were born conjoined at the forehead on June 12," Sigalas told Reuters. "Physically, they are developing naturally and are in good health."
