North Korea also mocked South Korea for criticizing those launches.
South Korea's military said earlier that at least one projectile was launched from the Sino-RI area of North Pyongan province, an area known to have one of North Korea's oldest missile bases where a brigade operates mid-range Rodong missiles.
It later said there were two launches from the nearby town of Kusong, where North Korea conducted the first successful flight tests of its Hwasong-12 intermediate-range missile and Hwasong-14 intercontinental ballistic missile, both in 2017.
Kusong is also home to missile test facilities that were critical to the development of North Korea's solid-fuel Pukguksong-2, which was successfully flight-tested for the first time in February 2017, in the North's first missile test after President Donald Trump took office.
South Korean President Moon Jae-in urged North Korea to refrain from actions that could impede diplomacy. In an interview with a television network, Moon also said Seoul will explore various options to help revive the talks, including providing food aid to the North and pushing for his fourth summit with Kim.
