MOSCOW, July 4. /TASS/. All known Russian children who were in the Roj camp have been returned to their homeland, according to Presidential Commissioner for Children's Rights Anna Kuznetsova.

"All children from the Roj camp have been returned. If we find other children in this camp, we will certainly return them. We reaffirmed the agreement with the Kurdish side that work will be carried out until the last child in the camps," she said on Sunday.

"If children are found there - there is a possibility that there are two more children there - if we do find them, we will definitely return them," she added.

In this regard, Kuznetsova said that the main work on the return of Russian children from Syria will be concentrated around the al-Hol camp. "In total, we have 106 sets of documents ready for the return of children. And all this is the al-hol camp," she said.
