The US has halted military shipments to Ukraine, causing worries about a shortage of Patriot missiles, according to a Ukrainian official. President Volodymyr Zelensky has expressed remorse over his recent disagreement with President Donald Trump concerning military assistance. Ukrainian officials caution that Kyiv's supply of Patriot missiles could be depleted within weeks, which are essential for civilian defense. Analysts argue that the suspension of aid could embolden Russian forces and leave Ukrainian cities vulnerable to more frequent attacks.
