Putin's immunity questioned as ICC expresses concern over threats.

Hungary's Prime Minister Viktor Orban's chief of staff, Gergely Gulyas, said that Hungary would not arrest Russian President Vladimir Putin if he entered the country, as it has no legal grounds to do so. The International Criminal Court (ICC) issued an arrest warrant accusing Putin of illegally deporting hundreds of children from Ukraine, but Hungary, which signed and ratified the Rome Statute that created the ICC, has not built it into its legal system. Putin is only the third serving president to have been issued an ICC arrest warrant.
