South Korean military said North Korea fired two projectiles

North Korea fired two unidentified projectiles on Tuesday morning, South Korea's Joint Chiefs of Staff said, hours after a senior diplomat announced Pyongyang would be willing to resume negotiations with the United States later in September.

The "short-range projectiles" were launched from around Kaechon in South Pyongan province at around 7:00 a.m. local time towards the east and flew about 330 km. Tuesday's launch was the eighth by North Korea since U.S. President Donald Trump and North Korean leader Kim Jong Un met at the heavily militarized border between the two Koreas in June. The launches came after North Korean Vice Foreign Minister Choe Son Hui said on Monday  Pyongyang was willing to have "comprehensive discussions" with the United States in late September at a time and place to be agreed.
