The United States has decided to supply Ukraine with long-range army tactical missile systems (ATACMS), an important boost to Kyiv’s capacity to target Russian military logistics at long range distances as the country prepares for a second winter at war. President Joe Biden told the Ukrainian leader, Volodymyr Zelenskiy, in a private meeting that a small number of the weapons would be transferred, NBC reported, citing US officials. Ukraine has been asking for ATACMS for months.

Ukraine has reported breaking through Russian defence lines in the Zaporizhzhia area in the country’s south, with a general leading the counteroffensive there saying the advance is still under way. “On the left flank [near the village of Verbove] we have a breakthrough and we continue to advance further,” Gen Oleksandr Tarnavskiy told CNN. He said progress was “not as fast as it was expected, not like in the movies about the second world war”, but it was important “not to lose this initiative”.

Nine people were killed and 16 injured, among them two generals, in a Ukrainian airstrike on Russia’s Black Sea naval headquarters in Crimea, according to the head of Ukrainian military intelligence. Kyrylo Budanov told the Voice of America that “among the wounded is the commander of the group, Col Gen [Alexander] Romanchuk, in a very serious condition. The chief of staff, Lt Gen [Oleg] Tsekov, is unconscious.” A Ukrainian missile hit the headquarters in Sevastopol on Friday. Russia’s defence ministry said one military serviceman was missing as a result.

Russia’s foreign minister, Sergei Lavrov, has said Ukraine’s formula for peace is “completely not feasible” and that the war will be resolved on the battlefield if Kyiv and the west stick to the plan as a basis for negotiations. Lavrov accused western powers of directly fighting Russia, in comments at the United Nations.

Lavrov said Russia left the Black Sea grain deal because promises to Moscow had not been met. On the latest proposals by the UN secretary general to revive the deal, Lavrov said: “We don’t reject them, they are simply not realistic.”

Lavrov said he would go to Pyongyang next month for more negotiations following agreements reached by Russian president Vladimir Putin and North Korean leader Kim Jong-un.

Three successive commanders of one of Russia’s most prestigious airborne regiments have either resigned or been killed since its invasion of Ukraine, the UK Ministry of Defence has said. That highlighted the “extreme attrition and high turnover in Russia’s deployed military, even amongst relatively senior ranks”, it said in its intelligence update.

Russian spies are using hackers to target computer systems at law enforcement agencies in Ukraine in a bid to identify and obtain evidence related to alleged Russian war crimes, according to Ukraine’s cyber-defence chief.

Norwegian police have arrested a former commander of the Wagner mercenary group on suspicion that he attempted to illegally re-enter Russia after seeking asylum in Norway earlier this year, the lawyer for Andrei Medvedev said.

Volodymyr Zelenskiy held an impromptu meeting with the head of the Sudanese sovereign council, Abdel Fattah al-Burhan, where they discussed Russia-funded armed groups. The meeting took place at Shannon airport in Ireland.

Sergei Lavrov told the UN general assembly the “time has come for mutual trust building” between Armenia and Azerbaijan and that Russian troops “will certainly help with this”.

Azerbaijani soldiers and Russian peacekeepers are working jointly to disarm separatist fighters in the ethnically Armenian enclave of Nagorno-Karabakh, an Azerbaijani army spokesman has said.

Andrey Kortunov, an adviser to the Russian foreign ministry and director of Russian international affairs council, has been on the BBC Radio 4’s Today programme discussing the strike on Russian navy’s Black Sea HQ.

Kortunov emphasised the “psychological” importance of long range missiles being used in the strike. “I think psychologically it’s important because it’s a long range missile - its destruction power is pretty significant. But militarily, I don’t think it really makes that big a damage – after all it didn’t hit any really critical military targets and the damage at least according to the reports we received is quite limited.”

Who opened investigations? Germany, Denmark and Sweden, a the leaks happened in their exclusive economic zones.

What have they found? German federal prosecutors seized objects from a sailing yacht in January and found traces of explosives.

Meanwhile, Sweden’s public prosecutor said the “primary assumption is that a state is behind it”.

What has Ukraine said? The New York Times reported in March that US officials had seen information suggesting it was done by a “pro-Ukrainian group”, without Volodymyr Zelenskiy’s knowledge. Zelenskiy has repeatedly denied Ukraine was behind the sabotage.

Could it be a false flag? Andreas Umland, an analyst at the Stockholm Centre for Eastern European Studies, views Russia as “the most likely” culprit. The Kremlin has denied responsibility.

Zelenskiy speaks to Canadian parliament after Justin Trudeau announces training for F-16 fighter pilots

Ukrainian president Volodymyr Zelenskiy delivered an impassioned speech at the Canadian parliament on Friday in which he thanked Canada’s military support to Ukraine, as well as hailed the historic and communal ties between the two countries. “You’re always on the bright side of history … I have no doubt that you will choose the side of freedom and justice,” he said.

Prime minister Justin Trudeau says Canada is going to make a longer-term, multi-year commitment that provides steady support for Ukraine, including money for 50 armoured vehicles. Canada will give an extra C$650m ($482m) in military aid to Ukraine over the next three years, Trudeau told the Canadian parliament. He will also send F-16 trainers for pilots and maintenance so Ukraine is able to maximise its use of donated fighter jets.

A Russian missile strike on civilian infrastructure in Kremenchuk in the central Poltava region of Ukraine killed one person and injured 15 others, governor Dmytro Lunin said on Friday via Telegram. He said one child was among the injured and that Ukrainian air defences downed one of the missiles launched. These claims are yet to be independently verified.

The Russian deputy prime minister, Alexander Novak, held a meeting with Russian oil company managers on Friday to discuss the domestic fuel market, the government said. Russia temporarily banned exports of gasoline and diesel to all countries outside a circle of four ex-Soviet states with immediate effect, the government said on Thursday, without a specified end date.

US president Joe Biden has told his Ukrainian counterpart Volodymyr Zelenskiy that the US will provide a small number of long-range missiles to help in Ukraine’s fight against Russia, three US officials and a congressional official told NBC News on Friday. The officials did not confirm when the missiles would be delivered and remain anonymous as they have not been authorised to speak on the subject publicly.

A Ukrainian air force spokesperson reportedly said that he had hoped the missile strike on the Russian Black Sea fleet HQ earlier on Friday had left a bigger hole in the building. Air force spokesperson, Yuriy Ignat, speaking on Ukrainian television, said that while he was pleased by the result of the strike, he had hoped the effects would be more dramatic. “I wanted a bigger hole to be honest,” he said.

Ukraine’s military said its forces had “successfully” struck the headquarters of Russia’s Black Sea navy in the Crimean port of Sevastopol on Friday. “On 22 September close to 12:00 (0900 GMT) Ukraine’s defence forces successfully struck the headquarters of the Russian Black Sea fleet command in the temporarily occupied Sevastopol,” Ukraine’s military said on Telegram.
