The girls were released after more than three years in captivity following a deal that saw five Boko Haram commanders exchanged for their freedom.
The scene of the reunion was tearful and emotional; however, numerous families at the reunion event told German news outlet DW that the real celebration could only begin when all of the missing girls had come home.
Their release takes to 106 the number freed by the militants so far, the government said. Still, Nigerian psychologist Fatima Akilu, who heads an organization that helps Boko Haram survivors, told NPR that the girls are symbolic of a dire situation that continues to plague northeastern Nigeria.

The girls are now receiving medical attention at a rehabilitation center in Abuja and will eventually return to school. More than 270 girls were abducted from their secondary school in 2014, sparking global outrage.

Mr. Nkeki expressed hopes that very soon the remaining girls still in captivity will be rescued. "I am just laughing, clapping my hands with all the family", one father said. Some have been radicalised and have refused to return.
He added that in a related development, troops of 242 Battalion, acting on a tip-off, rounded up 10 suspected Boko Haram smugglers. It is feared some of the captured girls may have been used in suicide bombings.
"For the 21 and three other girls that were earlier released, I wish to inform us that their psycho-social counseling is still in progress and, of course, they have started remedial classes".
