Panama has nearly 300 deportees from different countries detained in a hotel after being deported by President Donald Trump. They are not allowed to leave until international authorities organize their return to the countries they came from.

Authorities say that more than 40% of migrants will not return to their home country voluntarily. The migrants in the hotel rooms hung messages on the windows that read “Help” or “We are not safe in our country.”

The migrants were from 10 countries, mostly Asian, including Iran, India, Nepal, Sri Lanka, Pakistan, Afghanistan, and China. Panama has been used to deport some of these people because the U.S. is having difficulty doing so directly. Costa Rica was expected to receive a similar flight of third-country deportees on Wednesday.

Panama’s Minister of Security Frank Abrego stated Tuesday that the migrants receive medical care and food following a migration agreement signed between Panama and the U.S.

Panama has agreed to act as a transit country or “bridge” for deportees. The U.S. will cover all costs. The agreement was made public earlier this month, following Secretary of State Marco Rubio’s visit.

Last Thursday, Panamanian President Jose Raul Mulino announced that the first deportation flight had arrived. Mulino is under political pressure because of Trump’s threats to retake control of the Panama Canal.

Images of deportees peeking out of windows on high-rise hotel rooms and holding notes asking for help have caused alarm in Central America.

Abrego denies that the foreigners have been detained, even though they are unable to leave their hotel rooms which are guarded.

Abrego stated that 171 out of 299 deportees had agreed to return to their countries voluntarily with the help of the International Organization for Migration (IOM) and the U.N. Refugee Agency. U.N. agencies have been in contact with the remaining 128 migrants to try and find them a new home in a third country. Abrego stated that an Irish citizen who was deported had already returned home.

Abrego stated that those who refuse to return home will be held temporarily in an undeveloped Darien province, through which hundreds and thousands of migrants crossed in recent years on their way north.

On Tuesday, the Panamanian Ombudsman’s Office is scheduled to give more information on the situation of deportees.
