Śrīmad-Bhāgavatam
[Canto 9, Ch. 16]
Viśvāmitra, did not agree. Therefore Viśvāmitra, being angry, cursed them. “May all of you bad sons become mlecchas,” he said, “being opposed to the principles of Vedic culture.”
PURPORT
In Vedic literature there are names like  mleccha  and  yavana . The  mlecchas  are understood to be those who do not follow the Vedic principles. In former days, the  mlecchas  were fewer, and Viśvāmitra Muni cursed his sons to become  mlecchas . But in the present age, Kali-yuga, there is no need of cursing, for people are automatically  mlecchas . This is only the beginning of Kali-yuga, but at the end of Kali-yuga the entire population will consist of  mlecchas  because no one will follow the Vedic principles. At that time the incarnation Kalki will appear.  Mleccha-nivaha-nidhane kalayasi kara-bālam . He will kill all the  mlecchas  indiscriminately with his sword.
