The number of unaccompanied minors has more than quadrupled since March last year.
The newspaper noted that this is the highest figure for any month in at least the last 15 years. Compared to February, the number of detainees increased by 70 percent.
Thousands of children remain in special centers, and border guards increase the number of migrant families in the United States.
More than 18,700 unaccompanied children and teenagers were taken into custody in March, including at entry points, the New York Times reported.
According to the documents, that’s almost double the roughly 9,450 minors detained in February and more than four times the 4,635 minors who crossed the border unaccompanied last March.
