The head of Croatia's leading rights group was left red-faced on Tuesday after his trousers fell down during a photoshoot with President Kolinda Grabar-Kitarovic.

Ivan Zvonimir Cicak, who heads the Croatian Helsinki Committee for Human Rights, was proudly posing in the front row for a photo with the president when his trousers suddenly dropped to his ankles.

Luckily, Grabar-Kitarovic was holding a large award in her hands which slightly helped preserve Cicak's dignity.

She did not appear to react, remaining calm despite a brief glance downwards as he stooped to pull them back up. The award was presented to Cicak and the committee for their work ahead of international Human Rights Day which is marked on December 10. AFP
