A Russian missile strike overnight on August 20 caused a fire at an industrial facility in Ternopil, Ukraine, after an oil tank was hit, resulting in a significant emergency response. Over 90 firefighters and 21 units of equipment were mobilized to contain the blaze, which was ultimately localized by 6:50 AM with no reported casualties. Local officials reported thick black smoke over the city, but air and water quality assessments indicated no harmful substance excess. Residents were advised to limit outdoor activities during firefighting efforts. The attack is part of a broader series of strikes, including a missile attack in the Sumy Oblast, impacting energy infrastructure. While the Ternopil fire was managed, ongoing monitoring of air quality continues in the area.
