US urges more arms for Ukraine amid fears of expanding war

The U.S. pressed its allies Tuesday to move “heaven and earth” to keep Kyiv well-supplied with weapons as Russian forces rained fire on eastern and southern Ukraine amid growing new fears the war could spill over the country’s borders.

For the second day in a row, explosions rocked the separatist region of Trans-Dniester in neighboring Moldova, knocking out two powerful radio antennas close to the Ukrainian border. No one claimed responsibility for the attacks, but Ukraine all but blamed Russia.
