The American Humane Society has condemned the US government for apparently leaving many service animals behind after withdrawing from Kabul. Footage on social media showed the dogs in cages and roaming around the airport.

“I am devastated by reports that the American government is pulling out of Kabul and leaving behind brave US military contract working dogs to be tortured and killed at the hand of our enemies,” American Humane President and CEO Robert Ganzert said in a statement on Monday.

“These brave dogs did the same dangerous, lifesaving work as our military working dogs and deserved a far better fate than the one to which they have been condemned,” Ganzert continued.

Images circulating on social media in recent days showed the dogs confined in cages at Hamid Karzai International Airport in Kabul after their handlers had left the country. While the US military drew criticism for giving its own dogs seats on evacuation flights, those dogs are considered non-commissioned officers by the military and outrank their handlers. Unfortunately, the contract working dogs enjoy no such luxury.

The Taliban consider dogs unclean, and other animal activists in Afghanistan have backed up Ganzert’s concerns about potential mistreatment. For example, former British Marine Pen Farthing managed to evacuate 150 dogs and cats from his animal shelter in Kabul over the weekend. But told the Daily Mail on Monday that Taliban fighters stabbed one of his dogs on the way through a security checkpoint to the airport and shot two dogs he left behind with a friend.

The Pentagon insists that it didn’t leave any dogs in cages, “including the reported working dogs,” spokesman John Kirby said on Tuesday. Instead, Kirby claimed that the dogs were left in the care of Kabul Small Animal Rescue (KSAR), a local charity run by an American woman named Charlotte Maxwell Jones.

KSAR and several other animal charities attempted to get a large group of rescue dogs on board an evacuation flight. Still, the Pentagon reportedly denied them and ordered the military to turn the animals loose at the airport. Video footage showing dogs roaming on garbage-strewn tarmac appeared to confirm these claims.

However, a charity involved in the rescue operation, Veteran Sheepdogs of America, claims that while some rescue dogs were turned loose, they still care for more than 50 service dogs at the airport and are raising funds to fly the animals to Germany and on to the US. Other rescue workers and journalists have called the fundraising drive a “scam.”

The US evacuation mission wrapped up shortly before midnight on Monday, marking the end of a 20-year war in Afghanistan and leaving the Taliban once again in control of the country. Though more than 120,000 people were airlifted out in the preceding two weeks, the dogs weren’t the only ones left behind. “Hundreds” of Americans remain stranded in Kabul, Gen. Frank McKenzie, the head of US Central Command, told reporters, adding that the “diplomatic mission” to extract them would continue.
