Russia maintains attacks on Ukraine, as Kyiv is warned to brace for a possible major barrage

KYIV, Ukraine (AP) - Russia fired more than 100 drones and two ballistic missiles at Ukraine overnight, the Ukrainian air force said Tuesday, as the country's foreign ministry noted that Moscow's recent threat to hit Kyiv especially hard from the air brought nothing new.

Russia on Monday urged foreign citizens, including members of diplomatic missions, to leave the Ukrainian capital as quickly as possible and told residents to steer clear of military and government facilities. It said that "systemic strikes" on Kyiv were being prepared.

Russia has regularly bombarded Kyiv, often causing dozens of civilian casualties with every attack, since it launched an all-out invasion of neighboring Ukraine on Feb. 24, 2022.

Russia's Foreign Minister Sergey Lavrov told U.S. Secretary of State Marco Rubio by phone Monday that the U.S. should evacuate its diplomatic staff from Kyiv, a foreign ministry statement said. Rubio didn't say whether the U.S. State Department would take that step, but expressed concern during a trip to India that the "terrible" war in Ukraine could escalate further.

The Trump administration has tried for more than a year to stop the war. But its efforts yielded no significant breakthrough and are now on ice as Washington focuses on the Iran war.

There were no announcements of diplomatic departures from Kyiv. The European Union, French and Polish delegations publicly said that they would not leave.

The European Union summoned Russia's representative in Brussels to convey its concerns Tuesday, with European Commission spokesperson Anitta Hipper accusing Russia of "trying to sow panic."

French Foreign Ministry spokesman Pascal Confavreux called the Russian threat "new intimidation from Moscow."

The level of security threats posed by Russia to Kyiv and other Ukrainian cities "remains the same as in previous years and months," Ukraine's foreign ministry said in a statement late Monday.

Russia has continuously launched missile and drone attacks on the capital, it pointed out, adding that Ukraine was prepared to assist diplomatic missions seeking additional security measures.

Andrei Kartapolov, head of the defense affairs committee in Russia's State Duma, said that the Ukrainian parliament and presidential office aren't among potential targets.

Kartapolov said that possible attacks could aim at underground bunkers used by various branches of Ukraine's armed forces, security agencies and other government structures.

"Those are well-concealed and fortified facilities, and our task is to spot and target them with the weapons we have," Kartapolov said in remarks carried by Parlamentskaya Gazeta, the official publication of the Russian parliament.

Russia said its biggest missile attack of the year last weekend was in response to Friday's deadly Ukrainian drone strike on what Moscow said was a college dormitory in Starobilsk, a city in Ukraine's Russia-occupied Luhansk region.

But the Ukrainian General Staff said that its strike in Starobilsk hit the local headquarters of the Russian military's special drone unit.

Ukrainian President Volodymyr Zelenskyy said that sophisticated American-made air defense systems that Ukraine needs in order to stop Russian ballistic missiles are in short supply because of the Iran war.

"Unfortunately, there has been no progress for a long time with America on expanding the production of anti-ballistic capabilities," Zelenskyy said on social media late Monday, adding that Kyiv is working with Europe to improve its own anti-ballistic capabilities in sufficient quantities.

He said that Ukrainian battlefield gains in recent months have enabled it to "stabilize" the 1,250-kilometer (780-mile) front line in eastern and southern Ukraine, suggesting that Kyiv's forces are holding their own against Russia's bigger army.

Russia's spring offensive is floundering as Ukraine's midrange drone strikes disrupt its rear supply lines, according to the Institute for the Study of War.

Moscow's warning of major strikes aims to distract public attention from its "poor battlefield performance" and an economic pinch caused by war costs and international sanctions, the Washington-based think tank said late Monday.
