North Korea is reportedly sending military jets to the east of the country in the wake of US strategic bombers flying over the area last week. South Korea's Yonhaap news agency quoted the country's National Intelligence Service NIST report is saying that Pyongyang is also boosting its defenses in the east of the country after the US bombers fly over. At the same time, the NIST added that no immediate retaliation against the flyover was taken by Pyongyang in retaliation against the flyover, suggesting that North Korea might have failed to fully detect the US warplanes, according to Yonhaap. Earlier, the US State Department see Stager and Pacific affairs bureau spokesperson Katina Adams told Sputnik that the United States has not declared war on North Korea and that Washington continues to seek a peaceful denuclearization of the Korean Peninsula. The statement came hours after North Korean foreign minister Riyong Ho said that the DPRK has every right to take countermeasures against the United States, including shooting down American strategic bombers outside the DPRK's airspace, as Donald Trump declared war on North Korea.
