With Ukraine's President visiting the USA, and America announcing more military help to the embattled nation, Russia issued a threatening message.
In its first reaction to Zelenskyy's trip, Moscow said that if USA increases the supply of weapons to Ukraine, then it "does not bode well" for Kyiv, and will lead to an "aggravation of the conflict".
Meanwhile, during his meeting with Biden, Volodymyr Zelenskyy said that a big piece of good news was USA's decision to send Patriot missiles.
Addressing a press conference with Biden, Zelenskyy said, "I have good news returning home. President Biden announced a new package of defence support worth around $2 billion. The strongest element of this package is the Patriot battery system - something that will strengthen our air defence significantly."
