The United Kingdom has announced it will provide further drone and missile support to Ukraine after a meeting between UK Prime Minister Rishi Sunak and Ukrainian President Volodymyr Zelenskyy.

Mr Zelenskyy touched down at The Prime Minister's Chequers country residence in a helicopter, greeting Mr Sunak with a tight hug.

The pair discussed the continuation of aid from the UK, which includes hundreds of air defence missiles, other unmanned aircraft and long-range attack drones.

When asked to provide fighter jets — something Mr Zelenskyy has been hoping to acquire for many months — Mr Sunak once again denied the request, but put his country forward to play a "key part" in the creation of a coalition of allies that will supply jets.

Mr Sunak said the UK would begin basic training of Ukrainian pilots in the coming months.

"We want to create this jets coalition and I'm very positive with it," Mr Zelenskyy said.

"I see that in the closest time you will hear some, I think, very important decisions, but we have to work a little bit more on it."

"The conflict is at a pivotal moment," Mr Sunak said.

"It is important for the Kremlin to also know that we are not going away. We are here for the long term."

Mr Zelenskyy's visit to the UK is one stop on a wider tour around Europe canvassing leaders for further military aid in the war against Russia.

Storm Shadow shot down

Russia's Defence Ministry said a long-range Storm Shadow missile supplied to Ukraine by Britain had been shot down by Russian forces on Monday.

It was only last week that Mr Sunak announced the UK would be providing the missiles.

The ministry said in its daily briefing that it had shot down the cruise missile, as well as shorter-range US-built HIMARS-launched and HARM missiles.

Britain is the first country to publicly supply Kyiv with long-range cruise missiles, which will allow Ukrainian forces to hit Russian troops and supply depots far behind the front lines.

Moscow said on Sunday that Ukraine had used the missiles to strike industrial sites in the Russian-controlled city of Luhansk in eastern Ukraine.

Kremlin spokesman Dmitry Peskov said Russia viewed Britain's decision to supply the missiles "extremely negatively".

"Britain claims to be at the forefront among those countries that continue to pump weapons into Ukraine," he said.

Ukraine claims hospital hit

Four people have been killed in a Russian missile attack that hit a hospital in the eastern Ukrainian city of Avdiivka on Monday, regional governor Pavlo Kyrylenko said.

"The Russians attacked the city with missiles this morning, they hit a hospital," Mr Kyrylenko wrote on Telegram.

He posted photographs of a heavily damaged three-storey brick building that was missing a chunk of its side and had spewed rubble and debris onto the ground.

He called on residents of the small city in the industrial Donbas region to evacuate as fast as possible.
