Ukraine-Russia war latest: At least four dead in daytime missile strike on port city - as massive building on fire

As we reported a short time ago, the Duchess of Edinburgh has met with Volodymyr Zelenskyy in Ukraine, in what marks the first visit to the country by a member of the Royal Family since the war begin.

Sophie met the Ukrainian president and first lady Olena Zelenska and delivered a message to them on behalf of the King, Buckingham Palace said.

Throughout the day, we've been reporting on a Russian attack on the city of Odesa in Ukraine, which has killed at least four people. 

These images show a burning educational institution building, which was struck. 

Airline Finnair has said it is pausing flights to Tartu in eastern Estonia for the next month, due to GPS disturbances in the area.

"Finnair will suspend its daily flights to Tartu, Estonia, from 29 April to 31 May, so that an alternative approach solution that does not require a GPS signal can be put in place at Tartu Airport," the Finnish airline said in a statement.

Finnair last week had to divert two flights back to Helsinki after GPS interference prevented the approach to Tartu airport, although a spokesperson said the company did not now where the interference came from.

However, Tallinn seems certain as where the issues are originating. 

"It is a fact that Russia affects GPS devices in our region’s airspace," Estonia's foreign minister said via a spokesperson.

Margus Tsahkna added that Estonia will raise the issue of GPS interference with its neighbours, and intends to discuss it with the EU and NATO. 

GPS jamming and spoofing have grown worse in eastern Europe, the Black Sea and the Middle East, all areas close to conflict zones, according to industry group OpsGroup. 

More than 30 Ukrainian conscripts have died while trying to cross the border illegally to avoid mobilisation, a Ukrainian official has said.

Andriy Demchenko, spokesman for the State Border Guard Service, told Ukrinform that some men are prepared to pay "large sums" of money to groups promising to smuggle them across the border safely.

"Then they are faced with the fact that the route runs along a mountain river," he said.

Many conscripts have lost their lives after realising they didn't have the strength to swim the river, Mr Demchenko added.

"In total, since the beginning of the full-scale invasion, about 30 people have died trying to cross the border illegally," he said.

Such attempts occur "every day", he said.

For context: Ukraine has been under martial law since the Russian invasion in February 2022.

It lets draft officers call up men of a certain age to fight on the front line.

In April, Volodymyr Zelenskyy signed off a new law lowering the age of draft-eligible men from 27 to 25, in a bid to boost troop numbers in his depleted ranks.

The Duchess of Edinburgh has met with Volodymyr Zelenskyy in Ukraine, in what marks the first visit to the country by a member of the Royal Family since the war begin.

Sophie met the Ukrainian president and first lady Olena Zelenska and delivered a message to them on behalf of the King, Buckingham Palace said.

Her visit is aimed at demonstrating "solidarity with the women, men and children impacted by the war and in a continuation of her work to champion survivors of conflict-related sexual violence", the palace said.

Three women and a man have died after a Russian attack on Odesa.

A further 28 people have been injured, including two children aged five and 16. A pregnant woman has also been hurt.

Debris recovered from a missile that landed in the Ukrainian region of Kharkiv on 2 January was North Korean, the Reuters news agency is reporting.

Citing a United Nations sanctions monitor, Reuters said debris recovered was from a Hwasong-11 series ballistic missile - made in North Korea.

Three sanctions monitors travelled to Ukraine earlier this month to inspect the debris - and found no evidence that the missile was made by Russia. 

They "could not independently identify from where the missile was launched, nor by whom". 

"Information on the trajectory provided by Ukrainian authorities indicates it was launched within the territory of the Russian Federation," they wrote in an April 25 report to the UN Security Council's North Korea sanctions committee. 

"Such a location, if the missile was under control of Russian forces, would probably indicate procurement by nationals of the Russian Federation," they said, adding that this would be a violation of the arms embargo imposed on North Korea in 2006. 

International leaders have long accused North Korea of supplying Russia with weapons.

Both Moscow and Pyongyang have denied the accusations, but vowed last year to deepen military relations. 

The situation in Odesa is fast-moving after the city in southern Ukraine came under Russian missile attack this afternoon.

Three women and a man have died, bringing the total number of people killed to four, according to regional governor Oleg Kiper.

He said a further 28 people have been injured, including two children aged five and 16. A pregnant woman has also been hurt.

Four people are "fighting for their lives," he said in a Telegram post.

The number of people injured in Russia's missile attack on Odesa has increased.

Regional governor Oleg Kiper said he was aware of 17 injured people, of whom at least two are in a "serious condition". Separately, Odesa mayor Gennadiy Trukhanov said at least 20 people were hurt.

Emergency services continue to work at the scene, Mr Kiper said. Earlier, he reported that at least two people had been killed in the attack (see 17.46 post).

The Odesa region has been repeatedly targeted by Russia during the war.

Last month, a Russian ballistic missile attack on a residential area killed at least 20 people and wounded more than 70.

Ukrainian troops are still defending their positions on the frontline while grappling with depleted weapons supplies and increased Russian attacks.
