Why are Ukrainian drones targeting annexed Crimea's infrastructures?

Ukraine's intensified drone strikes on Crimea's critical infrastructures are turning the annexed peninsula into a focal point of the conflict, with targets including bridges, ferries, and oil storage facilities. This aggressive strategy by Kyiv appears to be effective, causing significant fuel and power shortages that have compelled Russian authorities to implement emergency measures. The escalating bombardments are dramatically impacting everyday life for Crimeans, highlighting the broader geopolitical tensions and the severe repercussions of Russia's 2014 annexation.
