Over 50 migrants were headed to the Italian island of Lampedusa on Sunday after a charity ship rescued them from an abandoned oil platform in the Mediterranean, where one woman gave birth.
The vessel Astral, operated by the Spain-based NGO Open Arms, rescued the 54 people overnight, the group said in a statement.
The migrants had been trapped on the oil platform for three days after their rubber boat shipwrecked following their departure from Libya on Tuesday, Open Arms said.
On Friday, one of the migrants gave birth to a boy, while another woman had given birth days before. Two other young children were among the group, Open Arms said.
Later Sunday, the charity said that, following the rescue of those on the oil platform, the Astral came upon another 109 people, including four people in the water.
That group, which included 10 children, had also departed from Libya, it said.
Open Arms said they provided life jackets to the migrants before they were rescued by another charity ship, the Louise Michel, which is sponsored by street artist Banksy.
The Louise Michel, a former French navy vessel, was transporting the migrants to a safe port in Sicily, Open Arms said.
It is not unusual for migrants crossing the Mediterranean on leaky and overcrowded boats to seek refuge on offshore oil platforms.
As of June 1, some 23,000 migrants had reached Italy by sea this year, according to the UN Refugee Agency.
