A right-wing radical group says all refugees entering Hungary illegally should be deported for reasons of national security and says it will hold anti-immigrant protests at refugee camps and along the border with Serbia.

Gyorgy Gyula Zagyva of the 64 Counties Youth Movement also said at a Friday rally that a 4-meter (13-foot) high fence that the Hungarian government wants to build on the border with Serbia, where most migrants enter the country, "doesn't solve the problem."

Zagyva, a former lawmaker from the far-right Jobbik party, said the group's protests would show that "if the Hungarian government does not turn back the African hordes, then we will."

Some 75,000 asylum seekers have registered in Hungary so far this year.
