"North Korea's nuclear weapons and missile development is a grave threat to peace and security in our world and it is unacceptable that others financially support this criminal, rogue regime", Trump said as he joined Japanese Prime Minister Shinzo Abe and South Korean President Moon Jae-in for a meeting in NY.
US President Donald Trump called the North Korean leader a "madman" on Friday, a day after Kim dubbed him a "mentally deranged US dotard" who would face the "highest level of hard-line countermeasure in history".
Kim on Friday threatened the "highest level of hard-line countermeasure in history" in a tirade against Trump's warning that Washington would "totally destroy" the North if the USA or its allies were threatened.
The patrols came after officials and experts said a small quake near North Korea's nuclear test site on Saturday was probably not man-made, easing fears Pyongyang had exploded another nuclear bomb just weeks after its last one.
Previous quakes from North Korea have indicated nuclear tests by the reclusive state, the most recent earlier this month. Kim's foreign minister told reporters this past week that the North's response to Trump "could be the most powerful detonation of an H-bomb in the Pacific".More news: Mexico natural disaster : All Indians are safe in there, says Sushma Swaraj
North Koreans gather at Kim Il Sung Square to attend a mass rally against America on Saturday in Pyonyang, North Korea.
The US president responded by saying Mr Ri and North Korean leader Kim Jong-un "won't be around much longer" if they continue their rhetoric.
In another dizzying development Saturday, what seismologists say was a minor natural disaster prompted speculation that Pyongyang could be conducting yet another weapons test.
North Korea has launched dozens of missiles this year, several flying over Japan, as it accelerates its program aimed at enabling it to target the United States with a nuclear-tipped missile.
A day earlier, Kim reacted to Trump's provocative speech at the U.N.by equating the USA president to "a frightened dog" and a "mentally deranged US dotard", employing an obscure insult for someone declining into senility.More news: India vs Australia Match Prediction, Who Will Win 2nd ODI?
Ri echoed Trump's words Saturday, saying it is the USA president who "is on a suicide mission". Trump has said he won't allow it, although the U.S.so far has not used military force to impede the North's progress.
"The fire roughnecks who enjoy playing with fire, will die in fire", the news agency said.
China is imposing new limits on trade with North Korea after the isolated country's latest nuclear test.
North Korea has been working on developing missiles that can reach the United States and its allies and pair them with a miniaturized nuclear warheads. The Pentagon said it was the farthest point north of the Demilitarized Zone separating North and South Korea that any US planes have flown in this century. The data comes after the United Nations Security Council unanimously voted on August 6 to impose a ban on exports of coal, iron, iron ore, lead, lead ore and seafood as punishment for intercontinental ballistic missile tests in July.More news: Russian hackers tried to access Washington state's voting systems, officials say
