North Korea has reportedly launched multiple short-range projectiles, according to the South Korean military.

While initial reports indicated North Korea fired off a salvo of missiles, it is now unclear exactly what the North may have launched.

This type of behavior is possibly a sign that Pyongyang's patience with Washington is running out after round after round of failed negotiations.

The South Korean military is reporting that North Korea launched several weapons into the sea, perhaps a sign that North Korea's patience with Washington is growing thin.

North Korea launched a barrage of unidentified short-range projectiles early Saturday morning local time, the South Korean Joint Chiefs of Staff said in a press release, according to the semi-official Yonhap News Agency. The weapons, which were initially identified as missiles, reportedly flew out to ranges of roughly 70 to 200 kilometers (43 to 124 miles).

At this time, it is unclear what North Korea has launched. The mysterious projectiles were fired from the east coast town of Wonsan.

North Korea's last missile test was conducted in November 2017, when the country launched a new type of intercontinental ballistic missile — the Hwasong-15.

As an apparent good-faith gesture to facilitate bilateral dialogue, Pyongyang proposed a self-imposed long-range missile and nuclear testing moratorium while in talks with the US. Round after round of failed negotiations, which included two leadership summits attended by President Donald Trump and Chairman Kim Jong Un, have left both sides feeling frustrated.

In November 2018, after an abrupt cancellation of a meeting between the US Secretary of State Mike Pompeo and his North Korean counterpart, the North tested a so-called "ultramodern tactical weapon," apparently an artillery piece.

Last month, North Korea tested a "new tactical guided weapon," reportedly components for a new anti-tank weapon.

A missile launch, while potentially intended to signal a desire for movement on bilateral issues, would not only undermine the president's claims of progress with North Korea, but it would also risk bringing Pyongyang and Washington back to the exchanges of heated rhetoric and shows of force that had many wondering if nuclear war was just over the horizon in 2017.

The latest weapons launch comes on the heels of a meeting between Kim and the Russian President Vladimir Putin, the specific details of which remain murky.

Trump was reportedly "fully briefed" on North Korea's actions by White House National Security Adviser John Bolton, who has been decidedly pessimistic in his view of negotiations with Pyongyang. Bolton has, in the past, argued in favor of using military force.
