According to the article, Russia has launched a series of strikes on Kyiv and other Ukrainian cities using Iranian-made kamikaze drones. These drones, known as Shahed-136 or Geran-2, are capable of carrying a small explosive charge and can be difficult to detect on radar. The strikes caused damage to residential buildings and critical infrastructure, with at least four people killed in the capital. Ukrainian officials have accused Iran of providing Russia with the drones, which Tehran has denied. The use of these drones marks a new phase in Russia’s military campaign, as it struggles to make significant gains on the ground. The article also mentions that Ukraine has been seeking more advanced air defense systems from its Western allies to counter the threat posed by these drones.
