The launches came immediately after North Korea said on Monday it was willing to restart nuclear talks with the United
States in late September.
Trump and Kim agreed then to restart working-level negotiations for denuclearization talks that had stalled since
an unsuccessful second summit between Trump and Kim in Hanoi in February.
A senior Trump administration said: "We are aware of reports of projectiles launched from North Korea. We are continuing to monitor the situation and consulting closely with our allies in the region."
North Korea has previously said its development of new weapons is to counter military threats and offensive pressures
against its own security.
