US military says there was no white phosphorus leak at its air base in South Korea

SEOUL, South Korea (AP) — The U.S. military said Thursday its investigations confirmed there were no white phosphorus leak at one of its air bases in South Korea, days after local authorities urged residents to evacuate over concerns about a suspected leak.

On July 28, the Pyeongtaek city government sent text messages advising its residents to move to safe places and avoid skin exposure, saying white phosphorus was leaked at the Osan Air Base in the city, which is just south of Seoul, the capital.

White phosphorus is a controversial chemical substance used in incendiary munitions and smoke shells. When ignited, it burns at extremely high temperatures and can set buildings ablaze and burn human flesh to the bone.

City officials said they lifted the evacuation alert later in the day after being informed that the U.S. military finished decontamination work. They said their earlier text messages were issued following consultations with the U.S. military and South Korean police and emergency offices.

The U.S. military said in a statement Thursday it has confirmed the crystallization and residue identified during a routine munitions inspection on the day was not white phosphorus nor contained traces of the substance.

It said that follow-up analysis concluded that the residue was non-hazardous surface corrosion resulting from environmental exposure over time. It said no injuries happened.

“We appreciate the city’s close partnership in keeping our community safe, and we thank everyone for their patience as our team worked to resolve this situation,” Col. Ryan Ley, commander of the 51st Fighter Wing, said, according to the statement.

The United States deploys about 28,500 troops in South Korea as deterrence against potential aggressions from North Korea.

The U.S. military presence, along with crimes involving U.S. service members and U.S. role in South Korea's tumultuous modern history, has been a source of anti-American sentiments among many in South Korea.

Earlier this week, eight South Korean students were detained for allegedly breaking into the Osan base while shouting anti-U.S. slogans.

SEOUL, South Korea (AP) — North Korea launched a short-range ballistic missile toward the waters off its east coast on Thursday, South Korea's military said, the latest in a series of weapons tests by North Korea this year.

The military detected the launch from North Korea's eastern coastal Wonsan area around 5 p.m. (0900 GMT), the South's Joint Chiefs of Staff said in a statement.

It said South Korea's military has bolstered its surveillance posture and is closely coordinating with the U.S. and Japan.

Japan’s Defense Ministry also said that North Korea fired a possible ballistic missile but there was no impact in or around Japan.

North Korea has been focusing on enlarging its nuclear and missile arsenals since leader Kim Jong Un’s high-stakes diplomacy with U.S. President Donald Trump collapsed in 2019. Experts say the North Korean leader wants international recognition as a nuclear state so that he can demand the lifting of international economic sanctions on North Korea.

Last month, Kim supervised tests of a nuclear-capable cruise missile and other weapons aboard a new 5,000-ton destroyer. After years of prioritizing ballistic missile development, Kim has increasingly turned his focus to naval capabilities, including the construction of a nuclear-powered submarine.

While outlining his five-year military goals at the Workers’ Party congress in February, Kim also called for intercontinental ballistic missiles capable of underwater launches.

In recent years, Kim has also boosted his diplomatic credentials by expanding ties with Russia. North Korea has supplied conventional weapons and troops to Russia to support its war against Ukraine.
