This past week has seen the most significant escalation in hostilities Ukraine has witnessed since Russia's full-scale invasion and marks a new chapter in the nearly three-year war.

The Biden administration’s authorization for Ukraine to use U.S. long-range missiles against Russia has escalated the Ukraine war and increased the likelihood of direct NATO-Russia conflict, according to Moscow.

Russia says the use of a new hypersonic missile strike on Ukraine was President Vladimir Putin's warning to the West that Moscow will respond to their "reckless" actions in support of Ukraine. Kremlin spokesman Dmitry Peskov says Russia had "no doubt" that the US had understood the warning from Mr Putin.
