The latest developments of the conflict between Russia and Ukraine. All times EDT:
8:52 p.m.: As the battle for Mariupol continues, Ukrainian officials have estimated that about 2,000 of their troops are inside the plant along with civilians sheltering in its underground tunnels.
Earlier Saturday, the Azov Regiment of Ukraine’s National Guard, which has members holed up in the plant, released the video of around two dozen women and children, The Associated Press reported. Its contents could not be independently verified, but if authentic, it would be the first video testimony of what life has been like for civilians trapped underground there.
The video shows soldiers giving sweets to children who respond with fist-bumps. One young girl says she and her relatives “haven’t seen neither the sky nor the sun” since they left home Feb. 27.
7:24 p.m.: Ukraine President Volodymyr Zelenskyy answered questions from the Ukrainian and international media during a rare live question and answer session in Kyiv.

6:51 p.m.: IAEA Director General Rafael Grossi said Ukraine has asked his agency for "a comprehensive list of equipment" it needs to operate nuclear power plants during the war with Russia, Reuters reported on Saturday. The list includes radiation measurement devices, protective material, computer-related assistance, power supply systems and diesel generators, Grossi said, according to Reuters.

3:15 p.m.: Ukraine President Volodymyr Zelenskyy criticized U.N. Secretary-General Antonio Guterres for visiting Moscow on Tuesday before traveling to Kyiv on Thursday. There is "no justice and no logic" in Guterres visiting Russia first, Zelenskyy said.
2:18 p.m.: Ukraine President Volodymyr Zelenskyy said U.S. Secretary of State Antony Blinken and Defense Secretary Lloyd Austin will visit Kyiv on Sunday. "Tomorrow, the American officials are coming to visit us.

Other residents were reportedly told to board buses destined for Russian-controlled Dukuchayevsk, which is about 80 kilometers to the north.

But Russia remains a member of the G-20, which represents industrial and emerging-market countries. A consensus of member countries is required to boot Russia from the G-20, but several countries, including China, Brazil and South Africa, have indicated that they support keeping Russia in the group.
10:27 a.m.: Agence France-Presse reports that at least five people are dead after a Russian strike on the Ukrainian port city of Odesa, according to the office of Ukraine's president. Earlier on Saturday, city officials reported that a missile strike hit "infrastructure" in Odesa.

Women and children account for 90% of those who left the country. Men between the ages of 18 and 60 are banned from leaving as they might be called up for military service.
9:16 a.m.: Russian forces are attacking a steel mill that is the last stronghold of Ukrainian forces in the strategic port city of Mariupol, according to an adviser to Ukraine’s presidential office.

Earlier this week, satellite photos showed what appeared to be rows and rows of freshly dug mass graves in the town of Manhush, west of Mariupol. The Russians have been accused of trying to conceal the slaughter of civilians in Mariupol.
