The evidence provided includes general Wikipedia information about the Black Sea Fleet and the Port of Novorossiysk, but none of the web search results or Wikipedia entries report the specific event of Ukrainian forces attacking two tankers from Russia's shadow fleet at the entrance to the Port of Novorossiysk. The claim is highly specific and lacks corroboration from the provided evidence.

The evidence provides general information about Volodymyr Zelenskyy (Wikipedia) and mentions him announcing sanctions (web search), and general information about Telegram (Wikipedia). However, none of the provided sources confirm that Zelenskyy announced the attack on the tankers specifically via the Telegram messaging app. The claim is based on a specific mechanism of announcement not supported by the evidence.

The web search results contain reports about rescue operations and drone use in conflict zones (e.g., 'Ukrainian military drone leads woman to safety amidst enemy fire'). The Wikipedia entries confirm the existence and location of the Donetsk Oblast. However, none of the provided sources confirm the specific details of an elderly woman being rescued using an unmanned ground vehicle in the Donetsk Oblast. The claim is too specific to be corroborated by the available evidence.

The web search results provide general news updates about the war (BBC, Reuters) and information about Ukraine's economy (Wikipedia). While the claim states Ukraine will continue to use long-range weapons to strike targets at sea, on land, and in the air, the provided evidence does not contain a direct quote or report from Zelenskyy making this specific commitment. Therefore, it cannot be corroborated.
