Four infants, two children and five women drowned Sunday on the dangerous crossing from Turkey to Greece after a small plastic boat carrying nearly 30 refugees sank in heavy seas near the eastern island of Samos.
Most of the victims were trapped in the cabin, Reuters reported.
A Greek Coast Guard spokeswoman confirmed the 11 victims who drowned included four babies.
Fifteen other passengers were rescued after the boat sank. There's an ongoing search for "one or two missing," the spokeswoman said.
All but one of the victims were retrieved from the sunken 20-foot plastic boat, which lies in waters 10 feet deep just yards off the Greek island's rocky coast.
Winds of up to 31 mph have been hitting the area.
