According to RT Arabic, the Egyptians were abducted in Sirte, late in the evening of Sunday, September 13.
Coptic Christians are among those kidnapped.
The Egyptian ministry has not issued a statement either confirming or denying the news.
Last February, the Islamic State in Libya abducted and slaughtered on video 21 Coptic Christians. Earlier, eyewitnesses had said that, after abducting a number of Egyptians, they released the Muslims while reserving the Christians for slaughter.
