Thirty people are missing following the collapse of six homes after heavy rain triggered severe flooding in western Germany, according to a local media report.
The properties collapsed last night in the German state of Rhineland-Palatinate, broadcaster SWR said.
Two firefighters drowned and the army was deployed to help stranded residents on Wednesday.
Around 25 more houses are in danger of collapsing in the district of Schuld bei Adenau in the hilly Eiffel region, it added.
The report described the situation in the rural district of Eifelkreis Bitburg-Prum as “extremely dangerous”.
A spokesman for the district told SWR a family-of-five were stranded in a property completely surrounded by water.
Rescuers are unable to reach the house by boat.
The deluge of rain and flooding has disrupted rail, road and river transport, with shipping suspended on the Rhine river.
Further heavy rainstorms are expected to hit southwestern Germany today, and could continue until Friday night, the German Weather Service warned.
