Hello and welcome to News Hour from the BBC World Service.

We're coming to you live from our studio in London.

I'm Leise Doucette.

In a moment, Russia warns the West not to allow Ukraine to use Western

arms against target inside Russia or else. That's our main story today. Also in the program,

devastating floods in Myanmar lead the military ruler to ask for international

assistance.

And as the funeral takes place of the Olympic athlete Rebecca Cheptigai, murdered by a former boyfriend, will speak to her coach about his friend.

I miss all the jokes, the laughs and the determination, the courage in training.

I really miss Rebecca. She has been one of the most

disciplined athletes, very determined, very committed in her career. She used to

talk to the athletes, the young athletes in a very proper way, just that we have really lost one of those whom we thought

she would mentors other young athletes.

That's all coming up in about half an hour so do stay with us. But we start with the war of words between Moscow, Washington and

London. It's hotting up as tensions escalate over the war in Ukraine. It seems to have been the top

issue on the agenda when Britain's Prime Minister

Sir Gere Stamer sat down with President Joe Biden in the White House.

The two leaders are being very coy about whether they've decided to shift their long-standing opposition to Ukraine's use of long-range

missiles they provide to attack Russia. After the meeting, Sir Kiir told journalists, the meeting

focused on strategy strategy not tactics.

This wasn't a meeting about a particular capability.

That wasn't why we got our heads down today.
