KHARKIV, Ukraine: Russian and Ukrainian drone strikes killed at least four people Wednesday, officials said, as the war between the neighbors dragged on for more than four years with no diplomatic breakthrough in sight.

The latest attacks came with a third round of three-party talks derailed by the war in the Middle East, despite pressure from Washington on both sides to agree to an elusive peace deal.

Kyiv said Russian drone strikes had killed two people and wounded seven more in the eastern Ukrainian city of Kharkiv.

Kharkiv, Ukraine’s second-largest city, which lies close to the Russian border, was encircled at the beginning of Russia’s invasion four years ago.

It has been attacked almost daily since Moscow’s forces were pushed back later in 2022.
