The United States is delivering artillery shells and mobile rocket artillery missiles to Ukraine, two U.S. officials told Reuters on Wednesday, days after President Donald Trump’s administration halted shipments of some critical weapons to Kyiv, writes Reuters.

The pause in some weapon shipments last week appears to have been tied to concerns that U.S. military stockpiles might be too low, officials had said.

Since then, Trump said he did not know who ordered the pause and that he would send more weapons to Ukraine, primarily defensive ones, to help the war-torn country defend itself against intensifying Russian advances.
