Ukraine: New Russian missile flew at 11 times the speed of sound for 15 minutes
Ukraine has started sharing details of its investigation into the new missile fired by Russia yesterday.
"The flight time of this Russian missile from the moment of its launch in the Astrakhan region to its impact in the city of Dnipro was 15 minutes," the main directorate of intelligence said in a statement.
It added that the weapon was "likely from the 'Kedr' missile complex".
"The missile was equipped with six warheads: each equipped with six submunitions. The speed at the final part of the trajectory was over Mach 11," it added.
Mach 11 is a speed equitable to8,440 mph - 11 times the speed of sound.
The "Oreshnik", fired yesterday, is one of Moscow's newest intermediate-range missiles.
Vladimir Putin said last night it travelled at 10 times the speed of sound and so could not be intercepted. Russian sources said the range was 5,000 km (3,100 miles), allowing Russia to strike most of Europe and the west coast of the US.
Russia claims another village in Ukraine
Moscow's forces have captured another village on the route to a key town, state news agency RIA reports, citing the Russian defence ministry.
The village of Novodmytrivka fell to Russia today, it said, although Ukraine has not confirmed the report.
It lies some 20km to Pokrovsk's south.
Pokrovsk, the sole source of coking coal for Ukraine's steel industry, has been amajor objective for Putin's military. Some reports say Russian troops now hold positions less than six miles from the town.

Russia using advanced aircraft for standard tasks, UK MoD says
The UK's Ministry of Defence says it has intelligence saying that Russia is being forced to use its advanced fighter jets for more standard missions.
The MoD said Russia's air force had failed to establish air superiority over Ukraine "despite technological and numerical advantage" and more than 1,000 days of war.
"Russia has resorted to using their tactical level aviation - such as SU-34 aircraft - as airborne artillery," it added, without explaining why.
A single Russian Su-34 fighter-bomber is thought to cost between $36m-$85m.
Using such an expensive and advanced craft for relatively straightforward operations (that other cheaper craft could carry out) increases the likelihood of losing such prized assets.
The MoD said that Moscow's effective use of drones had allowed it to recuperate its long aviation fleet and missile stocks.
Despite the challenges, Russia has been able to consistently target Ukrainian critical infrastructure.
The MoD said to expect more attacks on energy, military and other sites "as Russia attempts to break the will of the Ukrainian people".
Three-minute read: Ukraine frontline at risk of 'collapse' as Russian troops advance towards key town
By Michael Drummond, foreign news reporter
The frontline in Ukraine is at risk of "collapse" as Russian forces capture village after village, analysts have warned.
Kyiv's defenders, exhausted from nearly three years of fighting, are outnumbered and desperately in need of equipment.
What's more, their audacious incursion into Russia's Kursk region in the summer means some of their most elite troops are now bogged down across the border and unable to help shore up vulnerable spots along the frontline.
Russia's defence minister has said Moscow's forces are "accelerating" their advance in eastern Ukraine.
Back in August, Ukrainian forces launched a daring incursion across the border into Russia, supported by tanks and other armoured vehicles.
It appeared to catch the Kremlin by surprise and a portion of the Kursk region fell under Ukrainian control - and has been ever since. Some of Ukraine's best-trained and best-equipped units are helping in the defence of the Kursk salient.
The idea was that the loss of territory in Kursk would be so politically unacceptable to Putin that Russia would redeploy its most capable units from eastern Ukraine to try and liberate it, thereby relieving pressure on the frontline in Ukraine, says Dr Marina Miron, an expert in war studies at King's College London.
But instead, Russia seems willing to keep Ukraine bogged down in Kursk while it mounts punishing attacks along the frontline in Ukraine - with success.
Moscow's forces have been advancing in the last two months at their fastest rate since March 2022, according to open source data, capturing village after village.
"The risk is that the frontline along the Donbas will collapse," Dr Miron says. "Much faster, probably, because of this Kursk operation."
She said Ukraine should worry less about what's happening in Kursk and more about Russian advances towards the city of Toretsk and the key town of Pokrovsk - which both lie just to the west of Avdiivka.
"Those are very important logistical hubs and defence outposts for the Ukrainian armed forces, and losing them will give Russia the advantage to move forward to cities like Kramatorsk and Sloviansk."
Pokrovsk, the sole source of coking coal for Ukraine's steel industry, has been amajor objective for Putin's military. Some reports say Russian troops now hold positions less than six miles from the town.
And despite the US finally lifting restrictions on Ukraine using Western missiles to hit targets inside Russia, Kyiv's forces face big problems.
UK defence secretary John Healey warned on Thursday that the frontline in Ukraine is "now less stable than at any time since the early days of the full scale Russian invasion".
US received Putin's message loud and clear, Kremlin says
The Kremlin has no doubt that the US understood Vladimir Putin's statement yesterday, according to the Kremlin.
Putin's address to the Russian people, in which he said that Moscow had used a new missile in Ukraine in response to "Western escalation", was very comprehensive, understandable and logical, Kremlin spokesman Dmitry Peskov said.
"We would prefer Washington to listen to the statements the Russian president made several months ago in St Petersburg," he added.

He also said there remained "openness" to hold talks with the US.
He summed up what Putin said by firing the new missile and his address: "The main message is that the reckless decisions and actions of Western countries that produce missiles, supply them to Ukraine and subsequently take part in strikes on Russian territory cannot remain without a reaction from the Russian side.
"The Russian side has clearly demonstrated its capabilities. The contours of further retaliatory actions, if our concerns are not taken into account, are also quite clearly outlined."
Merch featuring picture of Putin with new missile on sale
Merchandise including T-shirts has been put on sale in Russia after the test of a new missile yesterday.
This example, pictured by an RIA reporter, shows a T-shirt with an image of Vladimir Putin and the "Oreshnik" missile being fired, along with pictures of Joe Biden.
The Russian president said his military had tested the new intermediate-range missile in a strike on the Ukrainian city of Dnipro yesterday, in response to Ukraine using US and British-supplied missiles on Russian soil.
Previously 'elite' Russian units now 'understrength' and 'increasingly obsolete'
Russian units previously regarded as "elite" by the Western world are understrength, misused and becoming ineffective, according to a leading thinktank.
The US-based Institute for the Study War said distinctions in quality between Russian units that existed before Moscow's invasion of Ukraine "have become increasingly obsolete because of the way Russia is prosecuting its war".
"Russian formations that were once considered 'elite' or more specialised in terms of the tactical tasks they were associated with, such as VDV or naval infantry units, are now essentially functioning as understrength motorised rifle units, relying on infantry-led frontal assaults to make tactical gains as opposed to employing any sort of doctrinally unique tactics," it said.
It also noted that Russian high command had been forced to "rush" new recruits to fill gaps in its units due to high casualty rates.
It explained how this may affect North Korean troops who have been sent to fight alongside them.
"North Korea's ability to learn and integrate lessons from fighting alongside Russia is likely to be significantly degraded if the Russian military command uses North Korean troops in the same highly attritional infantry-led assaults that it uses most Russian personnel," it said.
It said if Pyongyang's troops were used by Moscow in the same way as its own, North Korea should expect the same high casulty rates.
As a result, "the losses that North Korean forces accrue in combat on behalf of Russia will dilute whatever institutional lessons the North Korean military was hoping to learn by joining Russia as a co-belligerent against Ukraine".
Britain 'directly involved' in Ukraine war, Russian ambassador says
Britain is now "directly involved" in the Ukraine war after its Storm Shadow missiles were used to strike targets inside Russia, according to Moscow's ambassador.
Speaking to Sky News yesterday, Andrei Kelin also warned the West to carefully consider the lower bar Russia has established for using nuclear weapons.
It comes after Western allies green-litUkraine's use of long-range missiles to strike inside Russia this week after months of requests.

1,000-page document detailing German plans for war with Russia leaked
A 1,000-page document which details how Germany would respond to a war breaking out with Russia has been leaked by local media.
The document, named Operations Plan Germany, had its rough outline laid out by Frankfurter Allgemeine Zeitung.
The outlet said it lists key commercial buildings and infrastructure that should be protected by the German armed forces, and offers local businesses tips on how to respond to war - including preparing replacement staff should migrant workers leave Germany.
It also reportedly contained tips on awareness on drone surveillance, cyberattacks and other forms of espionage in local communities.
Additionally, it detailed how Germany would logistically manage hosting tens of thousands of NATO troops should that be required.
Russia has sent North Korea anti-air missiles, Seoul says
North Korea has been provided with Russian anti-air missiles in exchange for sending 10,000 to aid Moscow in its war against Ukraine, according to a South Korean official.
Seoul's national security adviser Shin Won-sik said Russia has provided North Korea with the missiles and other air defence equipment in an interview with South Korean broadcaster SBS.
Shin said Russia had given North Korea economic and military technology support, when asked what Pyongyang stood to gain from sending troops to Russia.
"It is understood that North Korea has been provided with related equipment and anti-aircraft missiles to strengthen Pyongyang's weak air defence system," Shin said.
He also claimed that North Korea had been given technology to support its satellite programme, following a failed attempt to launch a spy satellite earlier this year.
