Hungary's far-right Jobbik party says it has ordered one of its politicians to spend three days with a Roma member of the party to atone for racist comments made in 2011 and 2013.

Jobbik president Gabor Vona said Monday he gave the order to Janos Kotel because of earlier comments on Facebook in which he said, for example, that he would buy weapons to kill Roma.

Vona says Kotel's comments are "unacceptable" and "most strenuously rejected" by Jobbik though they were made while Kotel was a member of an unarmed citizen patrol at a time of racial tensions in eastern Hungary.

Jobbik politicians have often made racist comments, even in parliament.

Kotel easily defeated a candidate from the governing Fidesz party in a Sunday by-election for city councilor in Mezotur.
