Officials say a Russian drone barrage has targeted the center of Kharkiv, injuring nine people and damaging a maternity hospital in Ukraine’s second-largest city.

The more drones in a single attack, Kuzan says, the more Ukraine hard-pressed air defence units struggle to shoot them down. This forces Kyiv to fall back on its precious supply of jets and air-to-air missiles to shoot them down.

One of Russia’s most powerful men, Foreign Minister Sergey Lavrov, is set to visit North Korea this weekend, in a sign of deepening relations between Moscow and Pyongyang as North Korea gets pulled deeper into Russia’s war in Ukraine.

Russia hit the Ukrainian city of Odesa with a daytime drone strike on Friday. At least 11 people were injured, according to authorities.
