SEOUL, South Korea >> North Korea on Tuesday fired multiple short-range ballistic missiles toward its eastern sea, the South Korean military said, as the country continued its weapons demonstrations hours before the U.S. presidential election.

South Korea’s Joint Chiefs of Staff didn’t immediately specify the number of missiles detected or how far they flew. Japan’s Defense Ministry said the missiles were believed to have already landed at sea and there were no immediate reports of damages.

The launch came days after North Korean leader Kim Jong Un supervised a flight test of the country’s newest intercontinental ballistic missile designed to reach the U.S. mainland. In response to that launch, the United States flew a long-range B-1B bomber in a trilateral drill with South Korea and Japan on Sunday in a show of force. That drew condemnation from Kim’s powerful sister, who Tuesday accused the North’s rivals of raising tensions with “aggressive and adventuristic military threats.”

The latest launches came after South Korean officials said the North was likely to dial up its military displays around the U.S. presidential elections to command the attention of Washington. South Korea’s military intelligence agency said last week that North Korea has also likely completed preparations for its seventh nuclear test.

Outside officials and analysts say North Korea eventually hopes to use an expanded nuclear arsenal as leverage to win outside concessions such as sanctions relief after a new U.S. president is elected.

There are widespread views that Kim would prefer a win by Republican candidate Donald Trump, with whom he engaged in high-stakes nuclear diplomacy in 2018-19, seeing him as a more likely counterpart to give him what he wants than Democratic candidate Kamala Harris. During campaigning, Trump boasted about his personal ties with Kim, while Harris said she won’t “cozy up to tyrants and dictators like Kim Jong Un who are rooting for Trump.”

North Korean state media claimed last week that the Hwasong-19 it tested Thursday was “the world’s strongest” ICBM, but experts say the solid-fuel missile was too big to be useful in a war situation. Experts say the North has yet to acquire some critical technologies to build a functioning ICBM, such as ensuring that the warhead survives the harsh conditions of atmospheric re-entry.

Tensions between the Koreas are at their highest point in years as Kim has repeatedly flaunted his expanding nuclear weapons and missile programs, while reportedly providing Russia with munitions and troops to support President Vladimir Putin’s war in Ukraine.

According to U.S., South Korean and Ukrainian intelligence assessments, North Korea was estimated to have moved a total of between 10,000 and 12,000 troops to Russia.
