LONDON and Kiev — Russia launched an intercontinental ballistic missile toward Ukraine on Thursday, officials in Kiev said, but a Western official told ABC News the attack did not appear to be an ICBM.

It was instead a ballistic missile aimed at Dnipro, in southeastern Ukraine, the Western official said.

A Ukrainian official told ABC News that the Ukrainian military was “95% certain” the attack was carried out with an ICBM, but added that they were still examining the missile parts on the ground and had not yet reached a final conclusion had come.

The claim was not immediately confirmed by Moscow, with Kremlin spokesman Dmitry Peskov declining to comment and saying questions about it should instead be directed to the Russian Defense Ministry.

The Ukrainian Air Force announced on Thursday morning that it had tracked the launch of the ICBM, along with six additional missiles, all of which were aimed at the Dnipro region. The ICBM appeared to have been launched from the Astrakhan region in southwestern Russia, Ukrainian military officials said.

All the missiles were launched within about two hours, starting at about 5 a.m., Ukraine said.

All targeted businesses and critical infrastructure, but only the missile that Ukraine identified as an ICBM struck the city, Ukraine said. The six other missiles were shot down. There were no reports of casualties or significant damage, officials said.

The ICBM launch, if confirmed, would come amid concerns that the conflict between Russia and Ukraine could further escalate. Ukraine’s military launched U.S.-made ATACMS missiles toward targets in Russia for the first time this week, days after U.S. President Joe Biden authorized such use of the long-range weapons.

According to the Russian Defense Ministry, Kiev launched six ATACMS on targets on Russian territory on Tuesday.

Ukrainian President Volodymyr Zelenskyy said he would not confirm whether Ukraine had used ATACMS to carry out an attack on an ammunition depot in Russia’s Bryansk region, but said Ukraine has ATACMS and “will use all of them” against Russia.

Within hours of Russia announcing it had downed five ATACMS on Tuesday, the Kremlin announced that Russian President Vladimir Putin had updated the country’s nuclear doctrine, a move that lowered the bar for Russia to respond with nuclear weapons. Russian ICBMs can carry nuclear warheads, although it appeared the missile fired Thursday was not.

Following the warning, Ukraine fired British Storm Shadow long-range cruise missiles at Russia for the first time on Wednesday, a Ukrainian military unit involved in the operation told ABC News. At least 10 of those rockets hit an estate in the village of Marino, the unit said.

They targeted a command post where generals and officers of the North Korean army were present, the unit said. More than 10,000 North Korean troops are said to be operating alongside Russian forces in the Kursk region.

Ukraine’s 413th Separate Unmanned Systems Battalion, which helped provide fire control for the attacks, told ABC News that there was intelligence indicating the presence of high-ranking North Koreans.
