PARIS (Reuters) - Flames ripped through an apartment block in Paris, killing at least eight people and injuring 36 early on Tuesday, authorities said.
Prosecutors said they suspected the fire was a criminal act and a woman had been detained during investigations.
Firefighters scaled ladders to rescue residents from balconies on the eight-storey block on Rue Erlanger, near the Parc des Princes soccer stadium and the Roland Garros French Open tennis venue.
Red flames roared through windows into the early hours of the morning as scores of firefighters sprayed water onto the building in the capital's chic 16th district.
Interior Minister Christophe Castaner said around 0800 GMT that the fire was now "totally under control".
City government official Emmanuel Gregoire said the fire began on the upper floors shortly after midnight, and that the victims were all residents.
"It was a particularly violent fire," Captain Clement Cognon of the Paris fire service told BFM TV.
Paris prosecutor Remy Heitz told reporters that investigators suspected a "criminal" cause for the fire and that a woman, aged 40 and known to have history of mental health problems, has been placed in custody.
Paris Mayor Anne Hidalgo wrote on Twitter that the city was in mourning after the fire which came less than a month after a gas blast in central Paris killed four people.
