2/5/19 Yahoo News:

At least 10 people died and 37 were injured in an overnight blaze at an apartment block in Paris that police are treating as possible arson....

"One person who lives in the building has been arrested. She's a 40-year-old woman who has prior psychological problems," Paris prosecutor Remy Heitz said from the scene on Tuesday where smoke could still be seen rising from the area. "She apparently had a row with neighbours which ended badly and she set fire to the building," he added.
