Ten people have died after a fire broke out at an eight-storey building in south-western Paris.
Fire services confirmed that more than 30 people, including six firefighters, were injured – one person is in a serious condition.
Paris prosecutor Rémy Heitz said earlier that the fire may have been started maliciously.
Heitz said one woman, who lived in the building, had been taken into custody and an inquest has been opened.
The 40-year-old woman was arrested in the road immediately after the fire, Heitz added.
Fifty people were evacuated by ladders in the upmarket 16th arrondissement.
