North Korean leader Kim Jong-un visited the country's satellite test site on the west coast and called for its modernization, Pyongyang's state media said Friday.

The official Korean Central News Agency (KCNA) announced his visit to the Sohae Satellite Launching Ground, as Seoul and Washington jointly concluded Pyongyang's recent purported "reconnaissance satellite" development tests were those of a new intercontinental ballistic missile (ICBM) system.

Kim's inspection came amid concerns that the North could engage in further provocative acts namely an ICBM test under the disguise of a satellite launch following its veiled threat in January to lift its self-imposed moratorium on nuclear weapons and ICBM tests.

"He learned about and evaluated the present state of the ground, and advanced the task to modernize it on an expansion basis so that various rockets could be launched to carry multi-purpose satellites, including a military reconnaissance satellite, in the future," the KCNA reported in an English-language news article.
