New video footage shows an overcrowded fishing boat capsizing off the Libyan coast sending migrants tumbling into the sea.
There have been at least two shipwrecks in as many days as sea crossings accelerate because of good weather.
Five people were confirmed to have died when the fishing flipped over on Wednesday (May 25).
“I have been shouting, I have been using all the devices, all the acoustic devices we have to get in touch with them and tell them ‘Listen to me, sit down, trust us, we gonna save all of you’. But it was not enough. People kept on moving, jumping into the water, as much as we came closer with the boat, they were swimming and jumping in the water and we had to pick them up,” said Francesco Iavazzo, Bettica ship commander.
The Italian coastguard said it helped save 4,000 migrants on Thursday (May 26) in 22 operations.
Italy has helped rescue more than 10,000 since Monday (May 23).
Two five-year-old children suffering from hypothermia have been transferred to Lampedusa for urgent medical care after surviving a shipwrecks.
