North Korea

A North Korean soldier who defected to the South has reportedly been found to have antibodies linked to the Anthrax infection in his bloodstream.

This discovery has prompted concerns that Pyongyang may be attempting to develop biological weapons using the deadly disease.

The presence of the antibodies in the unidentified soldier means that he was either exposed to or vaccinated for anthrax.

Luckily, he must have been immune to the bacteria, according to South Korea's Channel A.

Anthrax can, however, kill within 24 hours if untreated, and about 2,000 people are believed to be infected each year across the globe.

South Korea's military does not yet have access to an anthrax vaccine and is unlikely to do so until the end of 2019.

It has not been confirmed if the unnamed soldier was the same one who was recorded making a dash across the border in November.

Mr Oh was shot several times by North Korean troops during the escape. He is currently recovering in a Seoul hospital.

The Washington Post reported in early December that US officials are increasingly concerned about the growing threat of biological weapons from North Korea.

Pyongyang is believed to have experimented with bacterial strains including microbes that cause anthrax, cholera and plague.

The Pentagon has ensured that Korea-bound troops are vaccinated for exposure to anthrax and smallpox, implying that biological warfare is a very real threat.
