Ukraine-Russia war live: Zelensky says Putin is ‘afraid’ as Moscow suffers Satan II missile failure

The RS-28 Sarmat intercontinental ballistic missile is designed to deliver nuclear warheads to strike targets thousands of miles away in the United States or Europe, but its development has been dogged by delays and testing setbacks.

The 35-metre-long RS-28 Sarmat, known in the West as Satan II, has a range of 18,000 km (11,000 miles) and a launch weight of over 208 tonnes.

Russian media say it can carry up to 16 independently targetable nuclear warheads as well as Avangard hypersonic glide vehicles, a new system that Putin has said is unmatched by Russia’s enemies.

Since the start of the conflict, President Vladimir Putin has said repeatedly that Russia has the biggest and most advanced nuclear arsenal in the world, and warned the West not to cross a threshold that could lead to nuclear war.

Putin said in October 2023 that Russia had almost completed work on the missile.

The Kremlin have continued to show a public disinterest in peace talks unless it involves the complete destruction of the Ukrainian state, the Institute for the Study of War (ISW) think tank has said.

ISW analysts noted that Ukrainian president Volodymyr Zelensky confirmed reports that Ukraine invited Russia to attend Ukraine’s second peace summit but that the Kremlin had not demonstrated any interest in participating.

Kremlin Spokesperson Dmitry Peskov recently said there is “no alternative” to Russian victory in Ukraine, reiterating Russia’s unwillingness to negotiate on terms other than Ukrainian “capitulation”.

“ISW continues to assess that the Kremlin is not interested in good faith peace negotiations with Ukraine and that the Kremlin will only invoke the concept of ‘peace plans’ and ‘negotiations’ to prompt the West to pressure Ukraine into preemptive concessions on Ukraine’s sovereignty and territorial integrity,” the situation report from the ISW said.

 World leaders will open their annual meeting at the UN General Assembly under the shadow of increasing global divisions, major wars in Gaza, Ukraine and, Sudan and the threat of an even larger conflict in the wider Middle East. Secretary-General Antonio Guterres previewed his opening “State of the World” speech to presidents, prime ministers, monarchs and ministers at Sunday’s “Summit of the Future,” saying “our world is heading off the rails — and we need tough decisions to get back on track.” He pointed to conflicts “raging and multiplying, from the Middle East to Ukraine and Sudan, with no end in sight” and to the global security system, which he said is “threatened by geopolitical divides, nuclear posturing, and the development of new weapons and theaters of war.”

At last year’s UN global gathering, Ukraine and its president, Volodymyr Zelensky, took center stage. Mr Zelensky will be in attendance this year.

A Russian guided aerial bomb attack on the eastern Ukrainian town of Kostiantynivka has killed one person and injured two, according to the Dontesk regional governor Vadym Filashkin.

The attack damaged two unspecified infrastructure facilities, Filashkin added via the Telegram messaging app.

The eastern town lies some 12 kilometers (8 miles) from Chasiv Yar, a town on high ground where Ukrainian forces are attempting to stave off Russian westward advances.

Moscow denies intentionally targeting civilians in its invasion of Ukraine, although it has killed thousands of them. It says its strikes on infrastructure aim to reduce Ukraine‘s ability to fight.

The Kremlin has said that people should re-listen President Vladimir Putin’s statements in St Petersburg to understand Russia’s response to a possible decision by the West to allow Ukraine to strike deep into Russia with Western missiles.

Russia will not test a nuclear weapon as long as the United States refrains from testing, Putin’s point man for arms control said on Monday after speculation that the Kremlin might abandon its post-Soviet nuclear test moratorium.

In St Petersburg in June, Putin said he could deploy conventional missiles within striking distance of the United States and its European allies if they allowed Ukraine to strike deeper into Russia with long-range Western weapons.

Russia has no alternative but to achieve all of its aims in the “special military operation” in Ukraine, Kremlin spokesman Dmitry Peskov has said.

Peskov said that as soon as the aims were achieved, the military operation would end.

Russian President Vladimir Putin has been adamant peace talks will only begin if Kyiv abandons swathes of eastern and southern Ukraine to Russia and drops its NATO membership ambitions.
