The Ukrainian military said a Russian missile strike on a training facility in the north of the country killed at least three reservists and injured 18.

KYIV, Ukraine (AP) — Russian missiles hit a Ukrainian army training ground, killing three soldiers and wounding 18 others, authorities said, targeting Ukraine’s efforts to make up a severe manpower shortage in the nearly 3½-year war.

Earlier in July, Trump set a 50-day deadline for the Kremlin to reach a truce with Kyiv or risk economic penalties, but the warning has not halted Russia's barrage of strikes. The wave of attacks came as Russia said its troops were pushing deeper into Ukrainian territory.
