Russia launching an intercontinental ballistic missile at Ukraine would mark a "clear escalation" by President Vladimir Putin, the European Union said after Ukraine accused Russia of such an attack.

Ukrainian President Volodymyr Zelensky has said that a Russian attack on Ukraine with a new type of ballistic missile was a "clear and severe escalation" in the war and called for strong worldwide condemnation.

Ukraine said Russia fired an intercontinental ballistic missile early at Ukraine early Thursday marking the first time the nuclear warhead-compatible weapon had been used in the two-and-a-half-year conflict.

A Russian intercontinental ballistic missile that Ukraine says was fired at the city of Dnipro on Thursday was an RS-26 Rubezh, Ukraine's Ukrainska Pravda media outlet reported, citing anonymous sources.

The attack comes after the Russia-Ukraine war marked 1,000 days of war without an end in sight. The war began after Russia started an unprovoked full-scale invasion of Ukraine on February 24, 2022.

KYIV (Reuters) -Russia fired an intercontinental ballistic missile during an attack on the Ukrainian city of Dnipro on Thursday, Kyiv's air force said, in what would be the first use in war of a weapon designed to deliver long-distance nuclear strikes. The launch, if confirmed, highlights rapidly rising tensions in the 33-month-old war after Ukraine fired U.S. and British missiles at targets inside Russia this week despite warnings by Moscow that it would see such action as a major escalation. Security experts said it would be the first military use of an intercontinental ballistic missile.

A video allegedly showing a Russian RS-26 ballistic missile strike on Ukraine’s Dnipro has raised global concerns. The missile, capable of carrying a nuclear warhead, was reportedly launched from Astrakhan. The Kremlin denies involvement as fears of escalation grow.

It is the first known use in the war of such a powerful weapon, with a range of thousands of kilometres.

Russia's president says the attack on Dnipro is a response to Ukraine's use of long-range US and UK weaponry.
