Agence France-Presse reports that “the United States on Saturday sternly admonished North Korea against acts that could “further destabilize” the region, amid claims that it successfully tested a new engine designed for an inter-continental ballistic missile that could reach US shores.”  

“‘We have seen the reports of North Korea’s claims to have developed new engine technology for its ICBMs,’ read a statement from State Department Deputy Spokesman Mark Toner.”  

“‘We call on North Korea to refrain from actions and rhetoric that further destabilize the region and focus instead on taking concrete steps toward fulfilling its commitments and international obligations,’ Toner said.”
