After hammering Russia, Ukraine freaks out, then suddenly begs Moscow to stop Black Sea attacks?

Ukraine has offered Russia a mutual halt to attacks on civilian shipping and grain infrastructure as the Black Sea battle intensifies. Volodymyr Zelensky said Moscow rejected Kyiv's proposal after demanding guarantees that Russian energy sites would also be spared. The diplomatic push comes after Ukrainian strikes damaged major grain terminals in Novorossiysk, while Kyiv's own Black Sea grain exports have plunged. With both countries crucial to global wheat supplies and attacks threatening vital trade routes, has the mounting economic cost finally forced Zelensky to seek a deal with Putin?
