Tension is rising on the Korean Peninsula after North Korea reportedly conducted a "very important test" at a missile site.

A statement by North Korea's Academy of National Defense Science issued Sunday said the test took place at the Sohae satellite launching grounds on Saturday afternoon.

Although North Korean state media did not specify exactly what was tested, the report has fueled concerns of military tension ahead of North Korea's proposed "year-end" deadline for resuming nuclear negotiations. The U.S. has been keeping tight surveillance on North Korea lately, deploying the RC-135S Cobra Ball aircraft which tracks missile launches.

"The Academy of the National Defense Science of the DPRK made a report on the successful result of the test of great significance to the Central Committee of the Workers' Party of Korea," said a statement carried by the Korean Central News Agency (KCNA), referring to North Korea by its official name, DPRK. "The results of the recent important test will have an important effect on changing the strategic position of the DPRK once again in the near future."
