Rome: The death toll from the migrant shipwreck off the coast of southern Italy has risen to 59, including 12 children, junior interior minister Wanda Ferro told journalists on Sunday.
The number of dead is set to rise further, she added.
The shipwreck took place near Steccato di Cutro, a seaside resort on the eastern coast of Calabria, the region that forms the tip of Italy's boot.
One survivor was arrested on migrant trafficking charges, the Guardia di Finanza customs police said.
Cutro's mayor, Antonio Ceraso, said women and children were among the dead. Exact numbers for how many children had died were not yet available.
The boat was carrying about 120 people and hit rocks "a few metres from the shore," the coast guard said, adding that the search for other possible survivors was still on.
Earlier, the Mayor of Cutro, Antonio Ceraso, told the SkyTG24 news channel that women and children were among the dead.
He said the migrants' wooden boat had "disintegrated" amid stormy sea conditions, with parts of the wreckage ruins strewn across some 300 metres of the coast.
His voice cracking up, Ceraso said he witnessed "a spectacle that you would never want to see in your life ... a gruesome sight ... that stays with you for all your life." Firefighters were searching the sea on jet skis, but conditions were harsh making the operation difficult, Calabria firefighters' spokesman Danilo Maida told Reuters.
Initial reports from ANSA and other Italian news agencies, spoke of 27 bodies washed up on the beach and more found in the water.
Italian news agency Adnkronos said the migrants caught up in the shipwreck came from Iran, Pakistan and Afghanistan, while ANSA said they came from Iran, Iraq, Afghanistan and Syria.
Italian Prime Minister Giorgia Meloni expressed "deep sorrow" for the deadly incident, and vowed to stop irregular sea migration to prevent more deaths at sea.
Her right-wing government has taken a hard line on migration since it took power in October, mostly by restricting the activities of migrant rescue charities with tough new laws.
"It is a huge tragedy which shows the absolute need to act firmly against irregular migration channels," Interior Minister Matteo Piantedosi said in a separate statement.
It was "essential" to stop sea crossings which, offering migrants the "illusory mirage of a better life" in Europe, enrich traffickers and "cause tragedies like today's", he added.
Pope Francis, a vocal advocate for migrants' rights, said he was praying for everyone caught up in the shipwreck during his Sunday address to crowds in St. Peter's Square.
Italy is one of the main landing points for migrants trying to enter Europe by sea. The so-called central Mediterranean route is known as one of the world's most dangerous.
According to the International Organization for Migration's Missing Migrants Project, 20,333 people have died or gone missing in the central Mediterranean since 2014.
