A hotel under reconstruction collapsed on a home in the Paris suburb of Montreuil, killing a woman and two children and injuring eight, officials said on Monday.
"There are unfortunately three people dead... a woman and two children, including a baby," Christian Lambert, the prefect of the Seine-Saint-Denis region northeast of Paris, told journalists.
Eight people were also taken to hospital, including five children and three adults, he said.
The dilapidated four-storey hotel, which had been condemned by local officials, collapsed at about 11:00 pm (2100 GMT) Sunday onto a single-storey home housing two families of Malian descent. An investigation was underway to determine the cause of the accident.
Rescue officials were continuing to search through the rubble of the two buildings on Monday and said the number of casualties may rise.
