Japan said Tuesday it has decided to impose additional sanctions on North Korea by freezing the assets of five more organizations over their involvement in Pyongyang's nuclear and missile development programs.

The additional sanctions, approved at a Cabinet meeting in the morning, follow North Korea's repeated test-firings of ballistic missiles toward the Sea of Japan since late September, including one earlier this month that flew over the Japanese archipelago for the first time in five years.

The five organizations include North Korea's Ministry of Rocket Industry and four trading firms, the Foreign Ministry said.
