Russia struck the southern Ukrainian port city of Odesa with ballistic missiles in a nighttime attack, injuring 14 people and starting a massive blaze, local officials and emergency services said.

The third attack on the city in a week hit a sorting depot belonging to Ukraine’s biggest private delivery company, Nova Poshta. No staff were injured, the company said in a statement, but the strike started a major fire. On Monday, six people were killed in a Russian missile strike on Odesa, and two days later three people died there after the Kremlin’s forces targeted civilian infrastructure.
