Russian air defences shot down 19 drones in the Leningrad region and debris from one "damaged a section of the oil pipeline near the port of Primorsk, and the pipeline is being safely burned out," regional governor Alexander Drozdenko said on Telegram. He said there were no casualties.  Ukraine has stepped up attacks on Russian infrastructure targets in recent months.  Primorsk, which is between the Finnish border and the key city of St Petersburg, was also attacked in March when an oil depot was set ablaze.
