(NEW YORK) — Russian President Vladimir Putin’s “special military operation” into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered “stiff resistance,” according to U.S. officials.

The Russian military has now launched a full-scale ground offensive in eastern Ukraine’s disputed Donbas region, as it attempts to capture the strategic port city of Mariupol and secure a coastal corridor to the Moscow-annexed Crimean Peninsula.

Here’s how the news is developing. All times Eastern:

Russia attacks Azovstal steel plant in Mariupol

Russian forces attacked a steel plant in the shattered Ukrainian port city of Mariupol on Saturday, according to Oleksiy Arestovich, an adviser to the Ukrainian president’s office.

In a briefing, Arestovich said Russian forces had resumed airstrikes on the plant and were trying to storm it, a reversal of Russian President Vladimir Putin’s order two days earlier.

Ukrainian officials estimate that about 1,000 civilians are sheltered in the plant along with the remaining Ukrainian fighters.

Mariupol evacuation fails

Busses promised by Russia to evacuate people from Mariupol did not arrive on Saturday.

At least 200 Mariupol residents had gathered near the Port City shopping center to be evacuated to Zaporizhia, adviser to the mayor of Mariupol Petro Andryushchenko said on Facebook.

“Instead of the buses promised by the Russian side, the Russian military approached Mariupol residents and ordered them to go away because “there will be shelling now.” In fact, with rough coercion, they dispersed people. The buses were not submitted for loading,” he wrote.

Russian missile attack kills 5 people in Odesa, including 3-month-old

Russian forces fired at least six cruise missiles at the Black Sea port city of Odesa, Anton Gerashchenko, an adviser to Ukraine’s interior minister, said on Telegram.

Five citizens were killed, including one 3-month-old baby and 18 people were injured, said Andriy Yermak, the head of the president’s office.

“These are only those who were found. And most likely, there will be more,” he wrote.

Ukrainian forces were able to shoot down several missiles, but at least one landed and exploded, Gerashchenko said.

“Residents of the city heard explosions in different areas,” Gerashchenko said in a post on Facebook. “Residential buildings were hit.”

“The only aim of Russian missile strikes on Odesa is terror. Russia must be designated a state sponsor of terrorism and treated accordingly. No business, no contacts, no cultural projects. We need a wall between civilization and barbarians striking peaceful cities with missiles,” Ukrainian Foreign Minister Dmytro Kuleba said in a tweet.

Ukraine resists Russian advance in the East: UK defense ministry

Despite the increased activity, Russian forces have made no major gains in the last 24 hours as Ukrainian counterattacks continue to hinder their efforts, according to the UK Ministry of Defense.

Russian air and maritime forces have not established control in either domain, owing to the effectiveness of Ukraine’s air and sea defense.

Despite their stated conquest of Mariupol, heavy fighting continues to take place frustrating Russian attempts to capture the city, further slowing their desired progress in the Donbas.

1 dead, 27 missing from Moskva ship, Russian Defense Ministry says

The Russian Defense Ministry announced that one service member died and another 27 crew members went missing from its Black Sea Fleet flagship vessel Moskva last week.

“The remaining 396 crew members were evacuated from the cruiser to the ships of the Black Sea Fleet,” the defense ministry said Friday.

The warship sank on April 14 following what the Ukrainians claimed was a missile attack. Russia did not acknowledge an attack on the ship and continued to say a fire broke out after ammunition detonated.

The defense ministry’s latest announcement contradicts its earlier statement that all Moskva crew members had been rescued.

European Council president holds call with Putin

European Council President Charles Michel and Russian President Vladimir Putin had a call Friday. Michel said afterwards on Twitter that he “strongly urged for immediate humanitarian access and safe passage from Mariupol and other besieged cities all the more on the occasion of Orthodox Easter.”

Michel also said he “firmly reiterated” the EU’s support for Ukraine and “condemnation and sanctions for Russia’s aggression.”

According to the Kremlin’s readout of the call, Michel asked Putin to have direct contact with Ukraine President Volodymyr Zelenskyy. The Kremlin said Putin “reaffirmed the well-known position on this matter, noting that such a possibility depends, in particular, on concrete results in the ongoing negotiations between Russian and Ukrainian representatives, during which the Ukrainian side is showing inconsistency and is not ready to seek mutually acceptable solutions.”

UK to reopen embassy in Kyiv

The United Kingdom announced Friday that it will soon reopen its embassy in Ukraine’s capital, Kyiv.

The U.K. Embassy in Kyiv, in northern Ukraine, was forced to temporarily close in late February due to Russia’s invasion. A contingent of British staff remained in western Ukraine to provide humanitarian and other support. U.K. Prime Minister Boris Johnson confirmed Friday that the embassy will reopen next week, “dependent on the security situation,” according to a press release from the U.K. Foreign, Commonwealth and Development Office (FCDO).

“The extraordinary fortitude and success of President Zelenskyy and the Ukrainian people in resisting Russian forces, means we will shortly be re-opening our British Embassy in Kyiv,” U.K. Foreign Secretary Liz Truss said in a statement. “I want to pay tribute to the bravery and resilience of the Embassy team and their work throughout this period.”

The embassy premises in Kyiv are currently being made secure before staff return, starting with U.K. ambassador to Ukraine Melinda Simmons. The U.K. continues to advise its citizens against all travel to Ukraine, according to the FCDO.

Russia aims to ‘contain Ukrainian resistance in Mariupol,’ UK says

Russia’s decision to blockade a steel plant in Mariupol “likely indicates a desire to contain Ukrainian resistance” in the strategic port city “and free up Russian forces to be deployed elsewhere in eastern Ukraine,” the U.K. Ministry of Defense said Friday in an intelligence update.

The Azovstal Iron and Steel Works plant is the last holdout for Ukrainian fighters in besieged Mariupol.

“A full ground assault by Russia on the plant would likely incur significant Russian casualties, further decreasing their overall combat effectiveness,” the ministry said.

Meanwhile, heavy shelling and fighting continues across eastern Ukraine’s Donbas region as Russian forces seek to advance further toward settlements including Krasnyy Lyman, Buhayikva, Barvinkove, Lyman and Popasna, “as part of their plans for the region,” according to the ministry.

“Despite Russia’s renewed focus they are still suffering from losses sustained earlier in the conflict,” the ministry added. “In order to try and reconstitute their depleted forces, they have resorted to transiting inoperable equipment back to Russia for repair.”

Putin to speak with European Council president

Russian President Vladimir Putin will have a telephone conversation with European Council President Charles Michel on Friday before meeting with permanent members of the Russian Security Council, according to Kremlin spokesman Dmitry Peskov.

“Putin will now have an international conversation,” Peskov told reporters Friday. “It will be the President of the European Council, Michel. And then during the day, Putin is scheduled to have an operational meeting with the permanent members of the Security Council.”

The U.S. has assessed that the Ukrainian port city of Mariupol remains contested, and that Russian airstrike activity remains focused there and on the Donbas region, a senior U.S. defense official said Thursday.

Russia now has 85 battalion tactical groups, each made up of roughly 800 to 1,000 troops, inside of Ukraine, the official said. More of these groups are headed to the Donbas region, the official said.
