MARSEILLE, France — Rescuers in the southern French city of Marseille found the bodies of four people in the ruins of two collapsed buildings as the search for victims and survivors continued into a second night.

A woman’s body was recovered from the rubble Tuesday night, the Marseille prosecutor, Xavier Tabareux, said. The bodies of two men and another woman were found earlier in the day.

Several people remained missing after the adjacent multi-story structures collapsed Monday.

Interior Minister Christophe Castaner said air pockets under the debris meant there was “hope to locate and find someone that can be saved.”

Mr. Castaner said 120 police officers and 80 firefighters took part in the search-and-rescue operation, working day and night in the pile of beams and rubble.
