At least 59 people died, including 12 children, when a wooden sailing boat carrying migrants to Europe crashed against rocks near the southern Italian coast early on Sunday, authorities said.

The vessel, which sailed from Turkey and was carrying people from Afghanistan, Iran and several other countries, sank in rough seas before dawn near Steccato di Cutro, a seaside resort on the eastern coast of Calabria.

The incident has reopened a debate on migration in Europe and Italy, where the recently-elected right-wing government's tough new laws for migrant rescue charities have drawn criticism from the United Nations and others.
