South Korea's foreign ministry strongly denounced North Korea's defiant ballistic missile launches on Tuesday, vowing to take the necessary diplomatic actions to tighten the screws on the communist country, South Korea's News Agency (Yonhap) reported. 
"The (South Korean) government strongly condemns the latest launch, which is a blatant violation of relevant United Nations resolutions and a provocation threatening the safety and peace of the Korean Peninsula as well as the region," Cho June-hyuck, the Ministry of Foreign Affairs' spokesman, said during a press briefing, urging North Korea to stop this kind of provocation immediately. 
Cho said South Korea will take the necessary diplomatic steps to stiffen international pressure on Pyongyang. 
"Currently, there is an anti-North Korea frame set up around resolution 2270 in the international community," Cho said, referring to ongoing global efforts to enforce the toughest-ever U.N. resolution adopted against the reclusive country. The resolution passed in early March is in response to North Korea's earlier nuclear and long-range missile tests. 
Earlier in the day, North Korea test-fired three ballistic missiles into the East Sea from its central western county of Hwangju. 
It was the communist country's first show of force after Seoul and Washington picked the southern county of Seongju, 296 kilometers southeast of Seoul, as the site to deploy the U.S.-built anti-ballistic missile interceptor system. 
The decision to bring in the Terminal High Altitude Area Defense (THAAD) took place after months of careful deliberation.
