The Times reported that eight children are among the asylum-seekers being held in the camp, called San Vicente.
Ghasemzadeh was one of about 300 people who were sent to Panama on a deportation flight earlier this week—first to be locked in rooms at the Decapolis Hotel in downtown Panama City, and then, in the case of about a third of the migrants, to be loaded onto buses headed for the camp near the Darién jungle.
At the hotel, the United Nations International Organization for Migration (IOM) met with the asylum-seekers, none of whom have criminal records, according to Panamanian officials—despite the Trump administration's repeated claims that people who have committed violent crimes will be prioritized for its wide-scale deportation operation.
"There is no world in which this is acceptable."
Officials confiscated the asylum-seekers' passports after they arrived at the hotel. At least one person attempted suicide while locked in the hotel, and another broke his leg while trying to escape.
"There is no world in which this is acceptable," said Elizabeth Dickinson, a senior analyst with the International Crisis Group, of the migrants' deportation and detention.
The IOM offered to coordinate flights to the migrants' home countries, but Ghasemzadeh, other Iranian Christians in the group, and some of the other people said they risk retribution—including possibly being put to death—if they return to the countries they left in order to seek asylum in the United States.
The BBCreported that 171 of the migrants—who came to the U.S. from India, China, Uzbekistan, Iran, Vietnam, Turkey, Nepal, Pakistan, Afghanistan, and Sri Lanka—agreed to be sent back to their home countries.
A local attorney seeking to provide some of the refugees with legal counsel, journalists, and aid groups have been blocked from speaking with the detained people and from seeing the conditions at San Vicente, the Times reported.
Times reporters gained information from two of the migrants who shared their locations using their cellphones, but Ghasemzadeh informed them Wednesday morning that officials at San Vicente were confiscating the phones.
"Please try to help us," she told the reporters after describing the camp as being extremely hot and "overrun with cats and dogs."
The treatment of the refugees, said Gillian Branstetter of the ACLU, is "a moral stain on all of us."
Panama's national security minister, Frank Ábrego, told a local news program Wednesday that the asylum-seekers are being held "for their own protection."
The Trump administration, which has arrested at least 41,169 people in its deportation raids, applied intense pressure to the Panamanian government to convince officials there to detain people who couldn't be deported to their home countries.
The government agreed Panama would be a "bridge" country for deportation flights after Secretary of State Marco Rubio visited the country, which followed Trump's threats to use military force to "recover" U.S. control of the Panama Canal.
In Panama, it is illegal to detain people for more than 24 hours without a court order.
On Thursday, a deportation flight is set to arrive in Costa Rica with 200 people from Central Asia and India. Costa Rica has also agreed to be a "bridge" country for Trump's deportation operation.
The news of the conditions in which the deported people are being detained came a day after the White House posted an "ASMR" video featuring the sounds of Trump's anti-immigration operation: the jangling of chains, locking of handcuffs around people's wrists, and steps taken by refugees as they board flights.
"ASMR, or autonomous sensory meridian response, is the pleasurable tingling some people experience in response to certain stimuli, often sound. There are millions of social media videos dedicated to the genre," wrote Natasha Lennard at The Intercept. "For the Trump administration, that pleasure is derived from the sounds of human bondage and racist exclusion."
"To me, the sound was a clarion call," she continued. "The thundering of a fascist machine that demands people of conscience stand up to gum up its works, that the clink of those chains should be silenced with blockages and blockades."
