Drones struck Russia's petrochemical hub Nizhnekamsk, killing 13 people,
including a child, and injuring about 40, foreign media report. Ukraine has
stepped up attacks on Russian oil-processing facilities this month after a lull
in late July when refineries carried out repairs and boosted nationwide fuel
output to ease shortages. Last week Kyiv struck five Russian refineries, adding
fresh pressure on domestic gasoline and diesel supplies.
