Russian President Vladimir Putin agreed on Tuesday to stop attacking Ukrainian energy facilities temporarily but declined to endorse a full 30-day ceasefire that President Donald Trump hoped would be the first step toward a permanent peace deal.

The White House described the agreement as the first step in a “movement to peace” it hopes will eventually include a full and lasting end to the fighting.

The two leaders say they will keep working toward the longer-lasting peace plan that the president has pushed for since taking office.
