A strike in the Ukrainian city of Kremenchuk has killed one and left a further 15 injured, Governor Dmytro Lunin said on his official Telegram channel.

One missile was shot down by air defence forces and civilian infrastructure was hit, he said.

According to Lunin, one of those injured is a child.

As President Volodymyr Zelenksy continues his visit to Canada, here's an at-a-glance look at today's developments so far:

• Ukraine's military has claimed responsibility for was behind the strike on the naval headquarters of Russia's Black Sea fleet in occupied Crimea
• A member of Russia's military is missing after the attack, Moscow said in an update, after initially reporting he had died
• A source at the Ukrainian Air Force has told the BBC that a type of cruise missile - Storm Shadow - supplied by Britain and France had been used in the attack on the base in Sevastopol
• Smoke was seen billowing from the building in videos on social media, while the Russian-installed governor of Sevastopol warned residents to stay away from the city centre
• The force of the strike was so powerful that it shattered the windows in nearby buildings and cut off power in some areas
• Zelensky has met with Canadian Prime Minister Justin Trudeau in Ottawa, as part of a North American visit to secure more military support for Ukraine
• He is due to address Canada's parliament later and give a joint press conference with Trudeau afterwards

Canada's cyber security services have issued a warning to people running government and critical infrastructure websites, calling for them to "adopt a heightened state of vigilance", the Canadian broadcaster CTV is reporting.

The warning to "bolster their awareness of and protection against malicious cyber threats" comes amid Volodymyr Zelensky's visit to Canada.

Speaking ahead of a bilateral meeting, Canadian PM Justin Trudeau told President Zelensky his visit was "an opportunity for Canadians to express directly to Volodymyr, and through him, to the Ukrainian people how strongly and unequivocally we stand with Ukraine".

In return, Ukraine's leader passed on "warm words and thanks" for the military and humanitarian aid provided to Ukraine by Canada.

Zelensky is due to address parliament in Ottawa shortly and then hold a news conference with Trudeau, before flying to Toronto to meet business leaders and then address a rally.

A little while ago, the president of Ukraine received a warm welcome from Canada's prime minister.

The Ukrainecast team of Lucy Hockings and Vitaly Shevchenko have just recorded their latest episode, and have been joined by our correspondent in Kyiv Orla Guerin to talk about the missile strike on Russia's Black Sea fleet headquarters earlier today.

While details are still filtering in, the team agrees that it's a major symbolic win for Kyiv.

“Ukraine has managed to strike right at the heart of Russian infrastructure in Crimea”, Guerin says, “and combined with recent strikes in Russia as well, it furthers the message Kyiv wants to send to Russia that it is vulnerable, too.

“It's not yet clear what the impact on operations will be”, Guerin continues, “given the immediate threat is the Russian ships themselves and the missiles they carry, but the symbolic damage is very clear.”

You can listen to the full discussion on Ukrainecast on BBC Sounds from 1930BST.

The attack on the headquarters of Russia's Black Sea fleet in occupied Crimea prompted evacuations in the surrounding area.

In this video, published on Telegram, external and verified by the BBC, children can be seen running from a building identified as a nursery school in Sevastopol as an air raid siren goes off.

A Ukrainian Air force spokesperson said he'd hoped the missile strike on the Russian Black Sea fleet HQ had left a bigger hole in the building.

The Kyiv Post, external reported that Yuriy Ignat told Ukrainian television that though he was pleased by the success of attack, he “wanted a bigger hole to be honest”.

"This is the best advertisement in the world of our weapons, which fly exactly on target," Ignat added.

The force of the missile strike on the Russian Black Sea fleet headquarters shattered windows of ten nearby residential buildings, the Sevastopol governor said on Telegram.

Mikhail Razvozhayev called for patience as electricity and gas has been cut off within the central ring of the city, and water supplies have been reduced as firefighters worked to extinguish the fire at the site of the strike.

Razvozhayev said no-one was hurt, while the Russian Ministry of Defence said one person was missing following the strike.

Ukraine used western supplied missiles in its strike on the headquarters of Russia’s Black Sea Naval fleet in occupied Crimea.

A source at the Ukrainian Air Force told the BBC that Storm Shadow – also known as Scalp – cruise missiles were launched.

Last week, they used the same models in an attack on a military base in Crimea which damaged a Russian submarine and landing ship.

Ukraine has claimed responsibility for today's missile attack on the Russian Black Sea fleet headquarters in Crimea.

The Ukrainian military says it "successfully" hit the naval base in Sevastopol, but gave no further details of the attack.

The missile strike on the Black Sea Fleet HQ points to a now familiar pattern of attack on Russian military assets in occupied Crimea.

One likely contender is the UK-supplied Storm Shadow cruise missile, launched from Ukrainian Su-24 “Fencer” swing-wing ground attack aircraft.

These missiles have a stated range of more than 150 miles (241km) and are equipped with either a blast or a penetrating warhead – the latter being more suitable for this sort of strike. Reports of a large hole in the building point towards this.

The other contender is the Ukrainian-developed R-360 Neptune. Originally designed as an anti-ship weapon, it has been comprehensively modified and improved for ground attack scenarios.

Last April, during the early weeks of the war, the missile was used to attack and sink the flagship of the Black Sea Fleet, the Moskva. Russia claimed the ship sank in a storm after a fire.

More recently, Neptune was credited to have been used to destroy one of Russia’s most advanced surface-to-air missile systems – the S-400 – in Crimea, dealing a blow to Moscow’s air defence capabilities in the region.

Here's a map showing location of the headquarters of Russia's Black Sea fleet in Sevastopol, Crimea, which has been hit by a missile strike.

General Mykola Oleshchuk, the commander of the Ukrainian Air Force, has appeared to suggest the air force was involved in the attack on the Russian Black Sea fleet HQ in Sevastopol:

"We told you there'd be more... while the occupiers are coming to their senses in Melitopol and air raid sirens are sounding in Sevastopol, let me thank Air Force pilots again!" he wrote on Telegram.

Russia tries to portray Crimea as a fortresspublished at 13:37 British Summer Time 22 September 2023

It appears Ukraine is continuing to target the occupied Crimean Peninsula with missile and drone strikes.

Last week, a Russian military base was hit, and a submarine and a warship destroyed. Russia tries to portray Crimea as a fortress.

Kyiv – which hasn’t acknowledged responsibility for this latest attack – is also trying to cut off Russian supply lines as it continues with its counteroffensive further north.

Ukraine, meanwhile, says Russia has started a new phase of what it calls “energy terror” ahead of winter.

But Kyiv says the country is better prepared than last year - when Russia targeted energy infrastructure with missile strikes.

If you're just joining us, here are four quick points to get you up to speed with the developments in Ukraine today:

• One person is missing after a missile strike on the headquarters of Russia's Black Sea fleet in Crimea, the Russian defence ministry says. Ukraine has not commented on the attack
• Ukraine's President Volodymyr Zelensky is in Canada today on an unannounced visit to rally support for his country
• Ukraine's prime minister accused Russia of attacking power infrastructure in what he called "energy terror" as winter nears
• A ship carrying vital supplies of grain has left a Ukrainian port on the Black Sea; it's the second ship to depart since the collapse of a deal with Russia to ensure the safe passage of non-military vessels

The Russian Defence Ministry has issued an "update" saying that one serviceman is missing, not dead after the Ukrainian attack on the navy HQ in Sevastopol.
