Ukrainian presidential adviser resigns over misinformation

An adviser to Ukraine's presidential office has resigned over an erroneous comment he made about a missile strike on a residential building in the eastern city of Dnipro on Saturday.

Dozens of people were killed in the attack.

Oleksiy Arestovych acknowledged on his social media account on Tuesday that he had made a "fundamental error." He posted a photograph of his resignation letter to the head of the presidential office.

Arestovych wrote that he offers his "sincere apologies to the victims and their relatives, the residents of Dnipro and everyone who was deeply hurt" by his "prematurely erroneous version of the reason for the Russian missile striking a residential building."

He had explained in an online interview with a Russian human rights activist on Saturday that the missile appeared to have fallen after it was shot down by Ukrainian air defenses.

The Ukrainian military denied his account, saying it had no weapons capable of shooting down the type of missiles that the Russians launched that day. Calls then began mounting in Ukraine for Arestovych to step down.
