Which Central American country had its deportation flights for unaccompanied minors blocked?

Guatemala is the correct answer because the country faced significant challenges related to its deportation flights for unaccompanied minors. Historical context demonstrates that Guatemala has been involved in complex immigration issues, particularly concerning the movement of children who travel to the United States seeking asylum or better living conditions. The Guatemalan government, in coordination with the United States, has at times encountered legal and logistical hurdles that hindered the effective deportation of minors who are unaccompanied. These obstacles can be due to various factors, including legal protections for minors, concerns about their safety upon return, and the need for thorough assessments of their circumstances before deportation can proceed.

In contrast, the other countries listed—Honduras, El Salvador, and Nicaragua—while also facing immigration issues, have not experienced the same specific legal impediments to deportation flights for unaccompanied minors as Guatemala. This highlights Guatemala's unique situation within the broader context of Central American immigration and child welfare policies.
