KYIV, Ukraine (AP) — Russia launched waves of missiles and drones at Kyiv early Monday, killing at least 12 people in an attack that exposed widening gaps in Ukraine’s air defenses, authorities said.

All of the ballistic missiles launched by Russia struck their targets, underscoring Kyiv’s need for more Patriot interceptor missiles — a point Ukrainian President Volodymyr Zelenskyy will likely reiterate at a NATO summit in Ankara, Turkey, this week. The attack came hours after Zelenskyy warned that a large-scale attack was imminent.
