The Paris prosecutor said 26 people have been formally identified after the capsizing last month of a boat in the English Channel that cost the lives of at least 27 trying to reach Britain.
The dead included seven women, a teenager and a girl aged 7.
The identity of one migrant remains unknown, Paris prosecutor Laure Beccuau said.
Ever-increasing numbers of people fleeing conflict or poverty in Afghanistan, Sudan, Iraq, Eritrea and elsewhere are risking the perilous journey from France, hoping to win asylum or find better opportunities in the UK.
The crossings have tripled this year compared with 2020.
European migration officials agreed to send a plane to monitor the shores of the English Channel for migrant activity, and pledged to work together more closely against migrant-smuggling networks.
