Russia-Ukraine updates: Russian missiles hit close to nuclear reactors: IAEA director

A Russian missile struck the Ukrainian port of Odesa on Saturday, just one day after Russia signed an agreement to allow grain ships to begin leaving the port.

The deal between Russia and Ukraine was mediated by Turkey and the United Nations. Fears of a global famine loomed as Russian ships had imposed a blockade on Ukraine exporting grain.

"It took less than 24 hours for the Russian Federation to launch a missile strike on the territory of the city of Odesa to question the agreement and promises made by it to the UN and Turkey in the document signed yesterday in Istanbul," the Ukrainian Embassy of Turkey said in a statement. "The Russian rocket is a spit of Vladimir Putin in the face of UN Secretary-General Antonio Guterres and Turkish President Recep Erdogan, who made a huge effort to reach the deal, and to which Ukraine is grateful."

The embassy added: "Ukraine stresses the need for persistent implementation of agreements to restore safe export of Ukrainian agricultural goods by the Black Sea from three ports: Odessa, Black Sea and South."

The Biden administration announced a new $270 million weapons package for Ukraine, which includes more HIMARS and drones. The administration is also in the very early stages of considering whether to send Ukraine fighter jets to counter Russia’s military, John Kirby, the National Security Council coordinator for strategic communications at the White House, said Friday

Kirby stressed that this is "not going to be something that they're going to be able to execute immediately or even in the short term," because these are advanced U.S. aircrafts and not ex-Soviet aircrafts.

"You’ve got to think about things like training, sustainment, maintenance that these aircraft would be required, you know, spare parts. There's a whole supply chain that goes with keeping any airframe in the air and all that has to be factored in," he said.

For now, Kirby said, the U.S. will continue to provide weapons and equipment through security packages like the new one announced Friday.

This package includes four more HIMARS advanced rocket systems, additional ammunition for those systems, anti-armor systems, vehicles and 36,000 rounds of artillery ammunition to go with the howitzers Ukrainians are using.

Russia and Ukraine have signed agreements to restart grain exports from Ukraine, said United Nations Secretary-General António Guterres.

The agreement between the two countries was mediated with Turkey and the United Nations.

The blockade on exporting grain from Ukraine had triggered fears of global famine.

The agreement "opens a path for commercial food exports from Ukraine in the Black Sea. It will help avoid a food shortage catastrophe for millions worldwide," Guterres tweeted. "It is a beacon of hope, possibility & relief."

The deal will allow for the transport of grain from three Ukrainian ports. Under the deal Ukraine will not de-mine its ports; instead there will be safe channels for cargo ships to sail through.

The agreement lasts for 120 days with the possibility of an extension.

According to Russian media, in exchange for agreeing to sign the deal, Russia received a guarantee from the U.N. to work on lifting sanctions on Russian agricultural and fertilizer exports.

Ukrainian first lady Olena Zelenska spoke to members of Congress on Capitol Hill Wednesday, saying, "Usually the wives of president are exclusively engaged in peaceful affairs: education, human rights, equality, accessibility. And maybe you expected for me to speak on those topics. But how can I talk about them when an unprovoked invasive terrorist war is being waged against my country?"

Zelenska said this marks the first time the wife of a president of a foreign county addressed members of Congress on the Hill.

Zelenska showed members of Congress several images and stories of carnage impacting civilians, including a photo of 4-year-old Liza who was killed by a Russian missile attack last week.

Liza's mother was seriously hurt, and "for several days, nobody dared to tell her that Liza has died," Zelenska said.

She highlighted an Odesa family who lost three generations of women to one missile, and a 96-year-old who survived Nazi concentration camps only to be killed in Kharkiv.

The first lady asked Congress to supply more air defense systems.

"Will my son be able to return to school in the fall? I don't know, like millions of mothers in Ukraine. Will my daughter will be able to go to university at the beginning of the academic year and experience normal student life? I cannot answer," she said. "We will have answers if we had air defense systems."

"America, unfortunately, knows from its own experience what terrorist attacks are and has always sought to defeat terrorists. Help us to stop this terror against Ukrainians," she said.

Zelenska received a standing ovation after her remarks.
