President Volodymyr Zelensky pushed ahead with his sweeping overhaul of the senior government ranks as the head of Ukraine’s ruling party released a slate of nine candidates for top cabinet positions Wednesday evening.

If Parliament approves the new candidates, which is expected, Ukraine’s foreign minister, Dmytro Kuleba, who resigned earlier Wednesday, will be replaced by Andrii Sybiha, the first deputy foreign minister, according to the party head, David Arakhamia.

The political upheaval came after a series of blistering Russian missile attacks and battlefield gains in recent weeks and before a vital trip by Mr. Zelensky to Washington, where he plans to reveal a “victory plan” for the war.

Mr. Zelensky said Wednesday that he was acting to bring a “new energy” to state institutions, hours after rescue workers pulled bodies from the wreckage of an overnight missile attack that killed seven people in the historic city center of Lviv, near the Polish border.

In one heart-wrenching scene, Yaroslav Bazylevych stood on the ancient cobblestone streets, covered in dust and blood, being stitched up by paramedics as rescue workers pulled the lifeless bodies of his wife and three daughters from the ruins.

“I don’t know what words to use to support the father,” the mayor of Lviv, Andriy Sadovyi, said in a statement.
