Twins conjoined by the liver have been born in India's northwestern Rajasthan state.
Around 1 million rupees (£10,000) is required to pay for the surgery to separate the two brothers. A local hospital is transferring the boys to New Delhi to perform the procedure.
According to the University of Maryland Medial Centre, the chances of giving birth to a conjoined twin are one in every 200,000.
The twins were born on the 13th of June
Conjoined twins are identical twins whose skin and internal organs are fused together in utero. They are always the same sex and they develop from the same fertilised egg, sharing the same amniotic cavity and placenta.
The Doctor treating the twins told ITN: "It's a very rare conjectural malfunction. Their heart is normal but they share a liver, one has the left lobe and the other has the right lobe."

Around 40-60% of the babies with the condition are still born and 35% of them survive for the first day. Sadly, the survival rate for the condition stands at 5-25%.
One of the earliest documented cases of conjoined twins were Mary and Eliza Chulkhurst, the girls were born joint at the hip in the year 1100 in the County of Kent, England.
