KYIV, Ukraine (AP) — A Ukrainian drone attack killed one person and wounded two others in a region some 260 miles east of Moscow, a Russian official said Monday, as fighting continued ahead of Friday’s Russia-U.S. summit in which President Vladimir Putin seeks a peace deal to lock in Moscow’s gains.

Ukrainian forces are increasing the intensity of long-range drone strikes deep into Russia ahead of Friday's planned meeting between Presidents Trump and Putin.

A series of Ukrainian drone strikes have reportedly caused damage to industrial facilities and resulted in casualties across various regions of Russia, according to statements from officials on both sides.
