Cities in Ukraine are the subject of Russian strikes almost every night. Kharkiv, close to the border in the north-east of the country, among the most regularly targeted.

Ukrainian officials are increasing cries of alarm for the country's Western allies to deliver more anti-aircraft defense assets, including modern American Patriot systems. American military aid to Ukraine, in particular, is drying up due to opposition from Donald Trump's Republican camp, which is blocking an envelope of some 60 billion dollars promised by President Joe Biden.
