The focus of some of our team then diverted to Sochi, Russia, where Vladimir Putin gave his annual address to the Valdai Discussion Club, all the while keeping an eye on the European Political Community summit in Spain.

Putin says Prigozhin jet was downed by 'hand grenades'
The Russian president said he had seen evidence from the investigative committee set up to look into the incident which suggested the plane was blown up from the inside.
The committee - which has not published its findings publicly - also found there was no evidence of an external strike on the aircraft, Putin said.
"Fragments of hand grenades were found in the bodies of those killed in the crash," he told an event in the Black Sea region of Sochi.

The US has said the attack on the cafe and grocery in Hroza is "incredibly horrifying for the people of Ukraine".
White House Press Secretary Karine Jean-Pierre told a briefing this was why "we're doing everything that we can to help Ukraine".
"Let's stop and think about what we're seeing: innocent people, who were killed by a Russian air strike while they were shopping for food at a supermarket. That's what they were doing.
"We have to continue to support the people of Ukraine because this is the horrifying nature that they live in every day," she said.
Last week, the US government passed a temporary funding bill to avoid a federal shutdown which did not include new aid for Ukraine.

Ukraine evacuated civilians from near the front line in Kupyansk in late AugustImage caption: Ukraine evacuated civilians from near the front line in Kupyansk in late August
Ukraine's President Volodymyr Zelensky visited the front line in the north-east only this week, because this region has been the focus of Russia's military offensive ever since the summer.
Last month, Russia said it had captured strategic heights near Kupyansk, just 30km (18 miles) to the east of Hroza.
There is no obvious reason why such a small village would come under attack, but it is within reach of that front line.
Ukraine recaptured Kupyansk and areas around it last autumn and Russian forces have spent the past few months trying to re-occupy it.
Six weeks ago Ukraine ordered civilians to be evacuated from Kupyansk because of Russian shelling.
President Volodymyr Zelensky said on Tuesday that the front line between Kupyansk and Lyman further south was "one of the hottest areas" of the war.
The latest civilian deaths are an indication of that.
Ten per cent of village's residents killed
Kharkiv regional head Oleh Synyehubov has confirmed that all the victims came from the village of Hroza.
According to 2020 census data, there were about 501 people who lived there.
That data is from before the war, so the population could be less now.
With the death toll now at 51 people, 10% of the village's pre-war population were killed in one Russian attack.
Putin claims Russian economy strong enough to sustain war effort
ReutersCopyright: Reuters
More now from Russian President Vladimir Putin, who is giving his yearly address to the Valdai Discussion Club in the Black Sea resort of Sochi.
Putin said that he expects the US to continue giving financial aid to Ukraine despite the domestic political crisis.
"Eventually they will probably find money, will print money," Putin told the conference.
"As regards Europe - the situation is more difficult because if in the US we are witnessing economic growth... the situation in Europe is much worse," he said.
Therefore, he said, Europe too can continue to support Ukraine but only "at the cost of seeing its economy and the lives of citizens of European countries worsen further".
He expressed confidence that Russia's own economy was strong enough to sustain the war effort.
"We have a stable situation," he said.
Putin said in Ukraine "we are defending our traditions, our culture and our people".
UN envoy 'appalled' by 'horrifying' attack on Hroza
The UN humanitarian co-ordinator for Ukraine says she is appalled by reports of the "horrifying" Russian attack on the village of Hroza.
In a statement, Denise Brown says she, the United Nations, and the humanitarian community send their "most heartfelt condolences to the bereaved families".
"Our thoughts are also with the people of Ukraine who had to witness today, once again, another barbaric consequence of Russia’s invasion," she adds.
Brown asserts that intentionally directing an attack against civilians or civilian objects "is a war crime."
"Intentionally launching an attack knowing that it would be disproportionate is a war crime," she adds.

Putin says Prigozhin jet was downed by 'hand grenades'
Just before we go, we can bring you an intriguing line from Vladimir Putin today - where he claimed a hand grenade detonating on board Yevgeny Prigozhin's plane was to blame for the crash in which the Wagner mercenary group leader and nine others were killed in August.
The Russian president said he had seen evidence from the investigative committee set up to look into the incident which suggested the plane was blown up from the inside.
The committee - which has not published its findings publicly - also found there was no evidence of an external strike on the aircraft, Putin said.
"Fragments of hand grenades were found in the bodies of those killed in the crash," he told an event in the Black Sea region of Sochi.
Priozhin, formally a close ally of Putin, died around two months after leading a convoy of troops to within miles of Moscow.
The Kremlin has repeatedly rejected any suggestion that it was to blame for the downing of his private jet.
