Russia fired more than 620 drones and long-range missiles overnight, killing at least six people in the latest wave of strikes, Ukraine said Saturday, adding that it was close to an agreement to receive more Patriot air-defence systems.

Three Ukrainians were killed in the southeastern Dnipropetrovsk region, where Russia captured a first village this week after a months-long incursion. In the neighboring Zaporizhzhia region — the site of a nuclear plant — two civilians were killed in the attacks, Gov. Ivan Fedorov said.
