The score is open: the first 20 tankers were hit during the night of July 15,” Brovdi wrote.According to Brovdi, the targets included 17 oil tankers, two gas tankers and one tugboat.“No piracy, Lavrov, just business. Yours, bloody,” he added.Brovdi’s remarks appeared to be a response to comments made by Russian Foreign Minister Sergey Lavrov on July 14, when he condemned Ukraine’s strikes on Russian vessels in the Sea of Azov during a joint press conference with Chadian Foreign Minister Abdoulaye Sabre Fadoul.Responding to a journalist’s question about whether the attacks could affect Russia‘s African partners and how Moscow might respond, Lavrov said:“You know, what the Ukrainian regime is doing isn’t even piracy. Pirates at least steal for themselves. Here, they neither take anything for themselves nor let others have it – they simply want to inflict damage and spread fear. It’s pure terrorism.”
