Spanish police say they have arrested two Cameroonian migrants on suspicion of killing up to 10 other migrants by pushing them from a boat into stormy waters in a fight over a prayer session.

Police said Thursday the two were arrested after several of the 29 survivors of the Dec. 3 African migrant boat crossing to Spain from Morocco told how a fight broke out when a Nigerian religious minister began praying that the boat would not sink.

Police said the Cameroonians blamed the worsening weather on the pastor.

The pastor and other Nigerians praying were among those allegedly pushed over board.

Police say there were some 50 people on the boat but that around 10 other migrants also died when they fell into the sea.
