North Korea is reportedly preparing for a third nuclear test — after it held one in 2006 and another in 2009 — AFP reported, citing a South Korean newspaper, Chosun Ilbo. The test may take place within two weeks.

Pyongyang test fired a failed long-range rocket in early April, which caused upset around the world because it was seen as a possible provocation and a disguised ballistic missile test. In response, US President Barack Obama said he would work to further cut North Korea off from the rest of the world and reconsider US food aid to the country.

This week, US Defense Secretary Leon Panetta accused China of providing assistance to North Korea’s missile program, a move that possibly violates UN sanctions on the country, according to Voice of America.

Beijing has denied the allegations.

Meanwhile, South Korea unveiled a new missile “to deter its neighbor,” Times of India reported. It coincided with major anniversary festivities in North Korea.
