"The whole world should clearly remember it was the USA who first declared war on our country", Minister Ri Yong Ho told reporters in NY, during the last day of the United Nations General Assembly.
North Korea's foreign minister called President Donald Trump's comments at the UN General Assembly a clear "declaration of war" that would lead the country to trying to shoot down USA strategic bombers even if they're not in North Korea's airspace, according to the BBC.
"Since the United States declared war on our country, we will have every right to make countermeasures, including the right to shoot down United States strategic bombers even when they are not inside the airspace border of our country", Ri said.
"For the past couple of days, we had earnestly hoped that the war of words between North Korea and the USA would not lead to action", Ri Yong Ho said in remarks translated for NPR by journalist Jihye Lee.
The foreign minister said that Trump, as America's current leader, had issued a "clear declaration of war".
Tensions have been rising between Mr Trump and North Korean leader Kim Jong Un in recent weeks.
USA bombers flew in worldwide airspace close to the North Korean coast Saturday, the farthest north any US warplane has flown since the turn of the century.
Christine Hong, associate professor at U.C. Santa Cruz says many North Koreans remember the bombings and civilian deaths during the Korean War from 1950 to 1953.
North Korea's foreign minister says President Trump's tweets about the Korean nation amount to a declaration of war and that under worldwide law, his country can legally shoot down US military planes - even if they're not in North Korea's airspace. The president also said he would "totally destroy" North Korea if the USA had to defend itself or its allies. "We need to do better on this, and will", the tweets continued. It is the latest in a series of hostile statements between the two countries.
In a six-part tweet from Twitter's public policy account, the company argued that Trump's speech was newsworthy and of "public interest", but said that it was planning to update its policy soon. "They are also working with North Korea". The social media network's statement comes after many called for Twitter to take action against the president saying it violated Twitter's rules that prohibit harassment and content that incites violence on its platform.
