Hours earlier, North Korea twice fired unidentified projectiles into the East Sea, according to South Korea's military.
The launches came shortly after the regime offered to resume denuclearization talks with the US in late September.
"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," the official told Yonhap News Agency. (Yonhap)
