The sister of Shahida Raza, a professional hockey player who died when the boat she was travelling on was wrecked off the coast of Italy on Sunday, has spoken to the BBC.
Shahida had paid traffickers to take her to Italy illegally, hoping to get treatment for her three-year-old son, according to her family.
At least 63 people are confirmed to have died in the shipwreck.
Caroline Davies, the BBC's Pakistan correspondent, reports from Islamabad.
It's four days since Saadia Raza last heard her older sister Shahida's voice. It was 7am on Sunday morning when the family received a call. Shahida was on a ship. After travelling on board for four days from Turkey, she told them, she was about to land in Italy.
"She was thanking God that she was nearly there," Saadia tells us over the phone from her home in Quetta, in south-west Pakistan. "She said she was scared that something could have happened while she was travelling across the water. She told us she couldn't believe it, that she would call her son and bring him for treatment when she arrived."
Then the call dropped. They couldn't reach her again.
Shahida was 27 years old when she died in the shipwreck off the coast of Italy. Passengers on board came from Afghanistan, Somalia, Syria, Pakistan, Iraq and Iran all trying to cross illegally to Europe. The wooden boat was thought to be carrying around 200 people; over 60 are known to have died.
Shahida had a very particular reason for making the dangerous journey, her family tells us.
"The one and only reason for her to take this trip was for her three-year-old son," Saadia tells us. "He is very unwell, part of his brain was damaged when he had a stroke at 40 days old because of a fever. It left his brain partially damaged and one side of his body from is head to his feet is paralysed."
Despite taking her son to different hospitals in Karachi, they could offer no treatment, Saadia says. Instead, they suggested Shahida take her son abroad in the hope that they might be able to offer him some treatment there. Shahida had been growing increasingly desperate.
"She said I can't see my son like this, I want him to walk like normal children, that's my only wish. She didn't want to see her son lying down helplessly," Saadia says.
After a long wait, Shahida's family learnt about the wreck online. They say they haven't spoken to anyone from the government since the news broke.
"It's like doomsday for our family," Saadia says. She starts to cry and stops our conversation to compose herself. Family friends have been visiting for the last few days to mourn. Local media is gathering outside the family house. "The day we heard that she is no more, it is only us and our God that know how we feel.
"We want the government to hand over her body as soon as possible. We don't need anything from anyone else now."
