North Korea Appears to Have Launched Another ICBM, South Says

SEOUL — North Korea launched what appeared to be an intercontinental ballistic missile off its east coast on Friday, in what would be its second ICBM test this month, South Korean defense officials said.

The United States and South Korean militaries were analyzing data collected from the launch to determine what type of missile the North had fired. But South Korean officials said early indications were that it had been an ICBM.

It was fired from the Sunan District of Pyongyang, the North Korean capital, at 10:15 a.m. local time, South Korea’s defense officials said.

North Korea has launched at least 88 ballistic and other missiles this year — more than in any previous year — in defiance of United Nations Security Council resolutions that ban the country from testing ballistic missiles, as well as nuclear devices.

North Korea last tested an ICBM on Nov. 3, when it fired six ballistic missiles to the east from three locations. One of them was an ICBM that covered only 472 miles while reaching an altitude of 1,193 miles. That test, which triggered aerial-attack alarms in Japan, was considered a failure, South Korean defense officials said.

North Korea also fired a short-range ballistic missile from Wonsan on its east coast on Thursday. That test came two hours after North Korea’s foreign minister, Choe Son-hui, warned that her country’s response would become “fiercer” if the United States, South Korea and Japan stepped up their military cooperation.

The leaders of those three nations met in Phnom Penh, Cambodia, on Monday and vowed to “work together to strengthen deterrence” against the North. They agreed to share warning data in real time to improve their countries’ ability to detect and assess the threat posed by incoming North Korean missiles, and President Biden reiterated the United States’ commitment to defend its East Asian allies with “the full range of capabilities, including nuclear.”

North Korea’s leader, Kim Jong-un, has repeatedly vowed to escalate his efforts to make the country’s nuclear arsenal and missile fleet bigger and more sophisticated. Analysts say Mr. Kim sees that as essential to ensuring his regime’s security, boosting his leverage in any future arms-control talks with Washington and tipping the balance of military power between North and South Korea in the North’s favor.
