In one flooded German town, the ground collapsed under family homes. In another, floodwaters swept through an assisted living center, killing 12.

Rescue workers across Germany and Belgium rushed Friday to prevent more deaths from some of the Continent’s worst flooding in years as the number of dead surpassed 125 and the search went on for hundreds of missing people.

Fueled by days of heavy rain, the floodwaters also left thousands of Germans homeless after their dwellings were destroyed or deemed to be at risk, and elected officials began to worry about the lingering economic effects from lost homes and businesses.

Elsewhere in Europe, dikes on swollen rivers were at risk of collapsing, and crews raced to reinforce flood barriers.

Sixty-three people perished in the German state of Rhineland-Palatinate, including 12 residents of an assisted living facility for disabled people in the town of Sinzig who were surprised by a sudden rush of water from the nearby Ahr River, authorities said.

German President Frank-Walter Steinmeier said he was “stunned” by the devastation and pledged support to the families of those killed and to cities and towns facing significant damage.

“In the hour of need, our country stands together,” Steinmeier said in a televised statement. “It’s important that we show solidarity for those from whom the flood has taken everything.”

By Friday evening, waters were receding across much of the affected regions, but officials feared that more bodies might be found in cars and trucks that were swept away.

A harrowing rescue effort unfolded in the German town of Erftstadt, southwest of Cologne, where people were trapped when the ground gave way and their homes collapsed.

Fifty people were rescued from their houses, county administrator Frank Rock told German broadcaster n-tv. Aerial photos showed what appeared to be a massive landslide at a gravel pit on the town’s edge.

“One has to assume that under the circumstances some people didn’t manage to escape,” Rock said.

Authorities cautioned that the large number of missing could stem from duplicated reports and difficulties reaching people because of closed roads and disrupted phone service.

After Germany, where the death toll stood at 106, Belgium was the hardest hit. The country confirmed the deaths of 20 people, with another 20 still missing, Belgian Interior Minister Annelies Verlinden told the VRT network Friday.

Several dikes on the Meuse Rriver that runs from Belgium into the Netherlands were at risk of collapsing, Verlinden said. Authorities in the southern Dutch town of Venlo evacuated 200 hospital patients due to the river’s looming threat.

Utility companies reported widespread disruption of electricity and gas service that they said could last for days or weeks.

The governor of North Rhine-Westphalia, who hopes to succeed Chancellor Angela Merkel as the nation’s leader after Germany’s election on Sept. 26, said the disaster had caused immense economic damage to the country’s most populous state. The number of dead in North Rhine-Westphalia stood at 43.

“The floods have literally pulled the ground from beneath many people’s feet,” Gov. Armin Laschet said at a news conference. “They lost their houses, farms or businesses.”

Manfred Pesch, a hotel owner in the small village of Gemuend, recounted how the floods came suddenly and rose to 2 meters (over 6 feet).

“Our hotel needs to be rebuilt,” he said. “We need a lot of help.”

Wolfgang Meyer, owner of a painting business in Gemuend, said his family escaped the rising water, but his business was swamped.

“The machinery, equipment, the entire office, files, records … everything is gone actually,” he said. “We’re going to have some work to do there.”

Malu Dreyer, the governor of Rhineland-Palatinate state, said the disaster showed the need to speed up efforts to curb global warming, which experts say could make such disasters more frequent.

She accused Laschet and Merkel’s center-right Union bloc of hindering efforts to achieve greater greenhouse gas reductions in Germany, Europe’s biggest economy and a major emitter of planet-warming gases.

“Climate change isn’t abstract anymore. We are experiencing it up close and painfully,” she told the Funke media group.

Steinmeier, the German president, echoed her calls for greater efforts to combat global warming.

“Only if we decisively take up the fight against climate change will we be able to limit the extreme weather conditions we are now experiencing,” he said.

The World Meteorological Organization said some parts of Western Europe have received up to two months of rainfall in the space of two days.

“What made it worse is that the soils were already saturated by previous rainfall,” WMO spokesperson Clare Nullis said.

She said it was too soon to blame the floods and preceding heat wave on rising global temperatures but added: “Climate change is already increasing the frequency of extreme events. And many single events have been shown to be made worse by global warming.”

The German military deployed over 850 troops to help with flood efforts, and the need for help was growing, Defense Ministry spokesman Arne Collatz said. He said the ministry had triggered a “military disaster alarm.”

Italy sent civil protection officials, firefighters and rescue dinghies to Belgium to help in the search for missing people.

In the southern Dutch province of Limburg, which also has been hit hard by flooding, troops piled sandbags to strengthen a 1.1-kilometer (0.7 mile) stretch of dike along the Maas River, and police helped evacuate low-lying neighborhoods.

Caretaker Dutch Prime Minister Mark Rutte said the government was officially declaring flooded regions disaster areas, making businesses and residents eligible for compensation. Dutch King Willem-Alexander visited the region Thursday night and called the scenes “heartbreaking.”

Meanwhile, heavy rain in Switzerland caused several rivers and lakes to burst their banks. Public broadcaster SRF reported that a flash flood swept away cars, flooded basements and destroyed small bridges late Thursday in the northern villages of Schleitheim und Beggingen.

Erik Schulz, the mayor of the hard-hit German city of Hagen, 50 kilometers (31 miles) northeast of Cologne, said a wave of other regions and ordinary citizens were offering to help.

“We have many, many citizens saying ‘I can offer a place to stay. Where can I go to help? … Where can I bring my shovel and bucket?’” he told n-tv. “The city is standing together, and you can feel that.”
