Its state-run KCNA news service alleged that it now has the ability to send a "large-size heavy nuclear warhead" across the Pacific following its test of a Hwasong-12 missile over the weekend.
The Security Council, which has imposed six rounds of sanctions on the North, discussed further possible actions at yesterday's meeting.
"The reality is that there is a high possibility of a military conflict at the NLL (Northern Limit Line) and military demarcation line", Moon said.
"In every test he [Kim] makes", Harris said, according to AFP, "it's a success because it takes North Korea one step closer to be able to deliver a nuclear-tipped missile anywhere in the world".
Kim In Ryong also dismisses allegations that North Korea was behind the recent global cyberattacks as "ridiculous", saying "whenever something odd happens it is the stereotype way of the United States and the hostile forces" to launch a campaign deliberately linking it to Pyongyang.
South Korean President Moon Jae-in has campaigned on a more moderate approach toward North Korea but has said it must change its attitude to arms development before dialogue is possible.
Haley said the Security Council is going to send a strong and unified message to North Korea that "the global community wants to support you but as long as you test, and as long as you continue your nuclear program, you are on an island by yourself".
South Korea's Unification Ministry deems that reopening of communications with North Korea is a good idea.
Although the devastating war between the democratic, wealthy south and the communist, impoverished north ended in 1953 without a peace treaty, there are channels of communication between them.
The paper also falsely claimed South Korean protesters were calling for the ouster of former President Park Geun-hye during their weekly "candlelight vigils" because of Park's conservative North Korea policy.
In July 2016, Washington and Seoul reached an agreement on placing a US THAAD system in South Korean territory.
"We want to look at the current sanctions in place, and we want to look at strengthening the sanctions".
Beijing has retaliated against Seoul over THAAD by suspending visits to South Korea by Chinese tour groups and trips to China by South Korean entertainers.
Haley answered Putin and others who have made similar comments about the United States: "What about North Korea intimidating us?"
North Korea was also under scrutiny by investigators looking for the source of a major cyberattack affecting more than 150 countries, but the European police agency said it was still too early to determine who caused the chaos.
