The attack caused at least one confirmed death and multiple injuries. Significant damage was reported to port infrastructure, oil storage facilities, and nearby civilian buildings. Rainfall mixed with combustion byproducts created a phenomenon described as "
black rain", depositing oily residue and soot across the city and surrounding areas. The resultant fires and smoke plume were so intense that the aftermath was commonly referred to as resembling a volcano. By late April 2026, the environmental impact had intensified significantly. Large-scale oil spills and toxic smoke from repeated strikes led to severe contamination of air, soil, and coastal waters. Russian authorities reported that more than 13,000 cubic meters of fuel oil and contaminated soil had been removed from affected areas, while beaches along the Black Sea coastline were heavily polluted and in some cases rendered unusable. Residents were advised to remain indoors, keep windows closed, and rely on bottled water due to concerns over air and water safety. Environmental experts, including Yevgeny Vitishko and Dmitry Lisitsyn, raised concerns about the broader ecological impact of the strikes. They noted risks related to air pollution, soil contamination, and the spread of oil products into marine ecosystems, warning that the full extent of the environmental damage may take time to assess. == Emergency response ==
