Long training time makes sending British jets to Ukraine impractical - Downing Street
Downing Street has rejected calls from former prime minister Boris Johnson to supply fighter jets to Ukraine.
Mr Johnson said he took the argument that the RAF's jets were too complicated to be used with a "pinch of salt".
But No 10 said it could take years to fully train a pilot, and the UK's focus was on providing help Ukraine could use in the short term.
Prime Minister Rishi Sunak's official spokesman said: "We will continue listening to the Ukrainians and consider what is right for the long term.
"But it's helpful to understand the situation, that the fastest training programme for a new pilot is approximately 35 months.
"The current UK fast jet training programme takes five years."
Mr Sunak's strategy was to "focus on how we can help Ukraine defend their country and push back this year", the spokesman added.
EU to train extra 15,000 Ukrainian soldiers
The European Union has pledged to train an additional 15,000 Ukrainian soldiers, the bloc's foreign policy chief Josep Borrell has announced.
"Russia brought war back to Europe, but Ukraine keeps fighting back," he tweeted.
"Glad to announce to Prime Minister Denys Shmyhal that EU Military Assistance Mission will train an additional 15,000 Ukrainian soldiers, taking the total number of EUMAM trained personnel to 30,000."
Troops will be given specialised training, as well as "technical instruction" for new equipment, including for Leopard 2 tanks.
The programme, which officially launched in November, aims to enhance the military capability of the Ukrainian Armed Forces to allow them to defend their country against Russia.
Russia claims to have gained ground in Ukraine's Donetsk region
Russia has claimed to have gained ground in Ukraine's eastern Donetsk region.
In its daily update, Russia's defence ministry said that its forces had defeated Ukrainian troops around the settlement of Vasylivka.
The area is just north of Bakhmut, which has been the focus of intense fighting for months.
Watch: Who is winning the war in Ukraine?
The Ukraine war has been rumbling on for nearly a year - but is either side actually winning?
Defence and security analyst Professor Michael Clarke has been exploring the answer to that very question.
"In Russia, it's now become acknowledged that this is a tougher proposition than they imagined back in February," he explained.
"But there is no way Russia thinks it will not prevail because they are Russia, they're a big power, they've got 144 million population, a big economy... therefore, once they put their minds to it, they will prevail."
He added that for Ukraine this is a war of "national survival", and one of the most interesting points of the invasion so far has been how patriotic the vast majority of Ukrainians are.
"That has actually given Ukraine a sense of nationhood that will propel it to be a different sort of state after this war," Prof Clarke said.

Joint air force drills between Russia and Belarus end after two weeks
Two-weeks of joint air force drills between Belarus and Russia have now come to an end, the Belarusian defence ministry has reported.
It said a wide range of tasks had been completed during the exercises, which it described as "exclusively defensive in nature".
The flurry of joint military activity in Belarus promptedfears in Kyiv and the West that Moscow could be preparing todrag its close ally further into the conflict in Ukraine.
Belarus is a landlocked country of 9 million people that borders northern Ukraine.
It served as a staging ground for Russian troops in the months before the invasion, and it has also hosted diplomatic talks between Russia and Ukraine.

Ukraine manages to repair several damaged power plants - here's why it's important
Ukraine has managed to repair several power units that were damaged in Russian missile attacks – helping to ease the country's electricity shortage.
Russian attacks on energy facilities have led to widespreadpower shortages and blackouts for millions of people since the war began.
Officials have said about 40% of the system has beendamaged as a result.
Why are the repairs important?
But while the power shortage has not been completely fixed, the repairs have improved the situation, meaning blackouts could become less frequent.
"The expected deficit at the evening peak will be about 19%of demand," the country's energy ministry said on Telegram.
The power shortage reached 25% at the end of January.
The ministry said warm weather could also help reduce demandon the strained power system.
It added that hostilities in the eastern regions of Donetsk,Kherson and Kharkiv were creating "the most difficult situationwith power outages".
National power grid operator Ukrenergo said in a separatestatement that power facilities had survived 13 Russian missileattacks and 15 waves of drones.
Two more missile strikes hit Kramatorsk
Two more missile strikes have hit the eastern Ukrainian city of Kramatorsk, a local official has reported.
In a Telegram post,the head of the Donetsk Regional Military Administration Pavlo Kyrylenko said the area "shuddered from the explosions".
It comes after three people were killed, and 20 others were injured, in a Russian missile attack that destroyed an apartment block in the city last night.
"The Russians launched two more missile strikes, again in the centre of the city, in residential buildings," Mr Kyrylenko said.
He added that some civilians had been wounded, but more details on the attack would be released later today.
Russia may stop officials taking holidays abroad - reports
Russian legislators are due to discuss a request by the founder of the Wagner Group to ban officials from taking foreign holidays during wartime, according to reports.
Yevgeny Prigozhin, who is also one of Vladimir Putin's closest allies, said it was unacceptable that officials and parliamentarians were going on holiday to countries that are hostile to Russia.
Local media reported that Vasily Piskaryov, head of the committee on security and anti-corruption in the State Duma or lower chamber of parliament, said legislators would take a look at whether changes should be made.
"This initiative... certainly deserves attention," Tass cited him as telling reporters.
Mr Prigozhin made the request in a letter to Mr Piskaryov that the Wagner Group made public.
The Ukrainian government, trying to clamp down on corruption, has banned officials from travelling abroad unless they had formal permission.
