The correct answer is option 4, North Korea. The leader of North Korea, Kim Jong-un, recently executed his own uncle, Jang Song-thaek, who was also his deputy. This shocking event took place in December 2013. Jang Song-thaek was a key figure in the North Korean government and was considered to be one of the most powerful individuals in the country.

It is important to note that this event reflects the authoritarian and oppressive nature of the North Korean regime. The execution of Jang Song-thaek was a demonstration of Kim Jong-un`s absolute power and his willingness to eliminate any perceived threats or dissent within the regime.

The execution of a high-ranking relative like an uncle was highly unusual and sent shockwaves throughout the international community. It highlighted the brutality and unpredictability of the North Korean leadership and further reinforced the image of a repressive regime that does not tolerate any form of opposition or dissent.
