Oleksiy Danilov, the secretary of Ukraine's National Security and Defense Council, said in a tweet on Friday that Kyiv will "test and use" any non-banned weapons to retake Crimea.
Ednews reports citing CNN that Ukrainian President Volodymyr Zelensky has repeatedly said since Russia's full-scale invasion that Ukraine plans to retake Crimea.
Crimea was declared annexed by Russia in 2014. After the revolt that forced pro-Russian President Viktor Yanukovych from office, Russian troops poured into the Crimean peninsula.
