At least 1,000 animals have been drowned in their own pens after a nearby river burst its banks.
The owners of the farm, in Villafranca de Ebro, Spain, had been directly warned by the local government about the high risk of flooding – but decided not to evacuate their animals.
Animal rights campaigners arriving on the scene filmed the tragic scenes unfolding at the farm as terrified animals thrashed against the rising currents.
In the video, the pigs can be seen squealing and struggling to stay afloat in the deep water.

The farm was flooded after the Ebro river burst its banks, and the Government of Aragon had previously warned farm owners to evacuate their animals.
An spokesperson from the Government of Aragon told reporters that 43 farms had been contacted before the floods and that 46,895 animals had been evacuated ‘without problems’.
However, the owners of the pig farm in Villafranca de Ebro seemingly ignored the warning, leading to the death of over 1,000 animals.
The government official said: ‘It is the owners of the plots of land who are responsible for saving their animals.’
Workers from the Service of Nature Protection (SEPRONA) of the Civil Guard tried to evacuate the pigs, but the water level was reportedly too high for them to complete the operation.
A herd of vows were also caught up in the floods and were pictured wading up to their knees in muddy water

Animal rights campaigners have now filed complaints against the owners for animal mistreatment
The Animalist Party Against Mistreatment of Animals (PACMA) recorded the horrifying scenes at the farm and told reporters: ‘If they had started (evacuating) on time, they would have saved them (the pigs).’
PACMA also filmed the scenes at a cow farm in the area where the owners appear to have abandoned their animals in the floods.
Dozens of cows can be seen stood in a flooded barn in the images.
PACMA have filed police complaints of animal mistreatment against two farm owners in the area.
No arrests have been reported.
