Ukraine has received a new shipment of US-made Patriot air defence systems. Zelensky stated that these systems will help protect civilians and vital infrastructure across the country from Russia's ongoing airstrikes.

The Patriot air defense system is designed to defend against tactical ballistic missiles, cruise missiles and aircraft.

Boeing said on Tuesday it has secured about $2.7 billion in a combination of multi-year contracts to supply a key guidance component for the Patriot interceptor missiles.

Russia has successfully tested its nuclear-powered Burevestnik cruise missile and will work towards deploying the weapon, Russian President Vladimir Putin said on Sunday, which comes as Moscow launched its second deadly attack on Ukraine in two nights.

Ukrainian President Volodymyr Zelenskyy painted his meeting last week with Donald Trump as a success that yielded progress on acquiring new air defense systems, a contrast from reports that Trump had berated him with obscenities in the White House.
