"Before that, they didn't know that they were Russian and that they had anything to do with our country," Kremlin spokesman Dmitry Peskov told reporters.
"And you probably saw that when the children came down the plane's steps that they don't speak Russian and that Putin greeted them in Spanish. He said 'buenas noches'."
"The children asked their parents yesterday who it was that was meeting them (in Moscow). They didn't even know who Putin was. This is how the 'illegals' work. They make such sacrifices out of dedication to their work," Peskov said.
