The first lady of Ukraine, Olena Zelenska, has warned that Ukrainians are at risk of death if Western countries do not continue their financial support.
Mrs. Zelenska made the statement during an interview for the BBC.
The first lady made the comments a day after Republican US senators blocked a key aid bill that would have provided more than $60 billion in support to Ukraine.
Zelenska told the BBC that the aid slowdown represented a "mortal danger" for her country:
"We really need help. Simply put, we cannot tire of this situation, because if we do, we die. And if the world gets tired, they'll just let us die. It pains us greatly to see signs that the passionate willingness to help may be waning. It is a matter of life for us. So it hurts to see this happening."
The White House has warned that US funding for Ukraine could run out soon, and Republicans have reached a deal to authorize more aid.
The UK has also urged politicians in Washington DC to agree a deal on Ukraine.
UK Foreign Secretary David Cameron said during a visit to Washington this week that the US was a "key partner" of the Western coalition backing Ukraine's war against Russia. (A2 Televizion)
