The five-second murder that shook the world

The assassination of North Korean leader Kim Jong-un's stepbrother was planned in great detail, according to a Malaysian media.

The assassination of Kim Jong-nam, the North Korean leader's half-brother, at the Malaysian capital's airport was planned so minutely that the killers needed only five seconds to carry it out, reports the New Straits Times newspaper.

According to the surveillance cameras, the two women were following Kim Jong-un's stepbrother, waiting for the appropriate time to execute their plan. The place chosen was the check-in area, where the North Korean was waiting to be attended to take a flight to Macau.

One of the killers began to talk to Kim Jong-nam to distract her attention, while the other, behind him, grabbed him by the neck and placed a handkerchief in his mouth, impregnated with poison, whose composition was still Unknown

The women quickly disappeared into the crowd, while Kim was treated at a medical facility at the airport, where he explained that he had a sharp sting in his eyes. An ambulance then moved him to the Putrajaya hospital, to which he would no longer live.

The cameras also captured how one of the killers then descended an escalator, ordered a taxi at a counter, and quietly left the airport.

Since Monday, three people have already been arrested for their alleged involvement in the crime.
