Nigerian woman, was on Monday delivered of a baby boy on board a rescue ship in the Mediterranean Sea.
A midwife on board the ship MV Aquarius described the birth as “normal in dangerously abnormal conditions”.
Medical charity MSF said because the baby was born in international waters, his nationality was still under debate.
The organisation said the baby’s parents had named him Newman Otas.
They had been making the perilous crossing with their two other children, aged seven and five, and were rescued just 24 hours before the baby was born. MSF communications officer Alva White reported the baby’s birth in a series of tweets on Monday.
“Just over an hour ago a baby boy was born on board the Aquarius. Mum, bub, dad and 2 big brothers are all well,” she said.
“The gorgeous little guy was born in international waters so his nationality is still under discussion.” Ms White said that such events were rare on rescue ships, although another baby was born on the Aquarius in May to a woman from Cameroon.
She said the 392 people now on board the Aquarius included seven pregnant women. Oqunbor said she had been “very stressed” on the rubber boat and had been having contractions for three days.
MSF midwife Jonquil Nicholl, who delivered the baby, said: “I am filled with horror at the thought of what would have happened if this baby had arrived 24 hours earlier – in that unseaworthy rubber boat, with fuel on the bottom where the women sit, crammed in with no space to move, at the mercy of the sea.
“And 48 hours previously they were waiting on a beach in Libya not knowing what was ahead of them.”
Thousands of refugees and migrants risk the dangerous crossing from Libya to Europe in search of a better life. Last year, more than 3,700 people are believed to have died attempting the journey.
