The Israeli Parliament (Knesset) approves the deportation of 400 children and their families whom Tel Aviv considers a "tangible threat" to Israel, Press TV reported.
Those affected by the new measure fail to meet the regime's criteria of speaking Hebrew and having lived in Israel for more than five years, AFP reported on Sunday.
They have been given only 21 days to return to their homelands.
The motion passed 13 to 10 after Prime Minister Benjamin Netanyahu threatened to table an earlier proposal, which he said "is much more harsh and dramatic," Ynetnews reported.
The Israeli Children organization warned that the decision targets kindergarten kids and other children, who "will fail to meet impossible bureaucratic demands."
The premier, however, said "illegal" immigration was a "tangible threat to the Jewish and democratic character" of Israel, the agency added.
