It was not immediately clear whether Ukraine would sign off on the agreement for a 30-day halt on strikes on energy and infrastructure, since Kyiv agreed last week to a more extensive U.S.-proposed ceasefire.

The White House described it as a first step toward to peace that it hopes will eventually include a maritime ceasefire in the Black Sea and an end to the war.

Zelenskiy, who had agreed to the full 30-day ceasefire, said after the Putin-Trump call that he would support the limited ceasefire, but urged the world to block any attempts by Moscow to drag out the war.
