"Odesa was attacked from the air. Some missiles were shot down by air defense,'' the city council said in a brief statement on the Telegram messaging app. It said fires were reported in some areas but gave no details on what the attacks may have targeted.

Ukraine's Ambassador to Germany, Andriy Melnyk, took aim at German President Frank-Walter Steinmeier. He accused the longtime politician of building a "web of contacts with Russia for decades."
"For Steinmeier, the relationship with Russia was and remains something fundamental — even sacred. No matter what happens, even the [Russian] invasion doesn't play a big role," Melnyk told the Tagesspiegel newspaper.
He also said that the German government hasn't been open in sharing its plans about potential weapons deliveries. The ambassador said he first heard about Berlin's plan to supply up to €308 million in weapons deliveries from reading it in the news.
"The communication could be a lot better," he said.

Journalists with the French news agency AFP counted at least 20 bodies in just one street. Reporters with the Associated Press said the bodies of at least six civilians were sprawled along a road and in a front yard.
"Those people were just walking and they shot them without any reason," a Bucha resident told AP, saying the departing Russian troops were behind the indiscriminate killings.

Round-up of events in Ukraine war on Saturday

Meanwhile, Baltic states sought to mount economic pressure on Russia by saying they'd stopped all imports of Russian gas on Saturday.
