Eight people feared trapped under rubble after an apparent explosion in Marseille.PARIS, April 9 (Reuters) - Eight people are not responding to calls and are thought to be under the rubble of two buildings that collapsed in an explosion early on Sunday in the southern French city of Marseille, local officials said.
The cause of the explosion was not yet known, Marseille prosecutor Dominique Laurens said.
The collapse caused a fire that has complicated rescue efforts and investigations, and it has not been brought under control, she told a news conference.
