South Africa's President Cyril Ramaphosa has addressed the nation to announce a raft of new measures to crackdown on illegal migration as tensions rise over anti-foreigner marches and frustrations about high unemployment, BBC reported. 

These steps include jailing employers who hire undocumented workers, setting up dedicated courts to speed up deportations of undocumented migrants and having a register with biometric data "for every person in the country" to stamp out identity theft.

But he also warned South Africans not to take the law into their own hands.
