President Trump and Russian President Vladimir Putin struck an agreement for a partial ceasefire in Ukraine, with Moscow agreeing to halt attacks on energy and infrastructure facilities, allow safe passage of Ukrainian ships along the Black Sea and begin talks to end the three-year conflict “immediately.”

It wasn’t clear if Ukraine accepted the terms of the deal.

It’s unclear when talks on details of a peace agreement would begin, but the White House said the negotiations would start “immediately” in the Middle East.

“The two leaders agreed that a future with an improved bilateral relationship between the United States and Russia has a huge upside. This includes enormous economic deals and geopolitical stability when peace has been achieved,” a White House readout of the call said.

In its own release, the Kremlin said Mr. Putin “responded positively” to Mr. Trump’s proposal to halt the energy and infrastructure attacks as well as assure “safe passage” in the Black Sea.

Mr. Putin also agreed to release 23 seriously wounded Ukrainian soldiers who are being treated in Russian hospitals and continue peace talks.

“The key condition for preventing the escalation of the conflict and working toward its resolution through political and diplomatic means should be the complete cessation of foreign military aid and the provision of intelligence information to Kyiv,” the Kremlin reported that Mr. Putin told Mr. Trump.
