Russia takes aim at urban areas

KYIV, Ukraine (AP) -- Ukraine's leader decried Russia's escalation of attacks on crowded urban areas as a blatant campaign of terror, while US President Joe Biden warned that if his Russian counterpart weren't made to "pay a price" for the invasion, the aggression wouldn't stop with one country.

"Nobody will forgive. Nobody will forget," Ukraine's President Volodymyr Zelenskyy vowed after Tuesday's bloodshed on the central square in Kharkiv, the country's second-largest city, and the deadly bombing of a TV tower in the capital. He pronounced the attack on the square as "frank, undisguised terror" and a war crime.

Biden used his first State of the Union address to highlight the resolve of a reinvigorated Western alliance that has worked to rearm the Ukrainian military and adopt tough sanctions, which he said have left Russian President Vladimir Putin "isolated in the world more than he has ever been."

"Throughout our history we've learned this lesson -- when dictators do not pay a price for their aggression, they cause more chaos," Biden said. "They keep moving. And the costs and threats to America and the world keep rising."

Biden devoted the first 12 minutes of his Tuesday evening address to Ukraine, with lawmakers of both parties repeatedly rising to their feet and applauding as he praised the bravery of Ukraine's people and condemned Putin's assault.

As Biden spoke, a 40-mile (64-kilometer) convoy of hundreds of Russian tanks and other vehicles advanced slowly on Kyiv, the capital city of nearly 3 million people, in what the West feared was a bid by Putin to topple the government and install a Kremlin-friendly regime.

The invading forces also pressed their assault on other towns and cities, including the strategic ports of Odesa and Mariupol in the south.

As the seventh day of the war dawned Wednesday, Russia found itself increasingly isolated, beset by the sanctions that have thrown its economy into turmoil and left the country practically friendless, apart from a few nations like China, Belarus and North Korea.

While the fighting raged, so did the humanitarian toll. Roughly 660,000 people have fled Ukraine, and countless others have taken shelter underground.

The death toll was less clear, with neither Russia nor Ukraine releasing the number of troops lost. The UN human rights office said it has recorded 136 civilian deaths, though the actual toll is surely far higher.

One senior Western intelligence official estimated that 5,000 Russian soldiers had been captured or killed in the biggest ground war in Europe since World War II.

Many military experts worry that Russia may be shifting tactics. Moscow's strategy in Chechnya and Syria was to use artillery and air bombardments to pulverize cities and crush fighters' resolve.

Britain's Defense Ministry said it had seen an increase in Russian air and artillery strikes on populated urban areas over the past two days. It also said three cities -- Kharkiv, Kherson and Mariupol -- were encircled by Russian forces.

Ukrainian authorities said five people were killed in the attack on the TV tower, near central Kyiv. A TV control room and power substation were hit, and at least some Ukrainian channels briefly stopped broadcasting, officials said.

Russia previously told people living near transmission facilities used by Ukraine's intelligence agency to leave their homes.

Zelenskyy's office also reported a missile attack Tuesday on the site of the Babi Yar Holocaust memorial, near the tower. A spokesman for the memorial said a Jewish cemetery at the site, where Nazi occupiers killed more than 33,000 Jews over two days in 1941, was damaged, but the extent would not be clear until daylight.

In Kharkiv, with a population of about 1.5 million, at least six people were killed when the region's administrative building on Freedom Square was hit with what was believed to be a missile. The Slovenian Foreign Ministry said its consulate in Kharkiv, located in another large building on the square, was destroyed.

The attack on Freedom Square -- the nucleus of public life in the city -- was seen by many Ukrainians as brazen evidence that the Russian invasion wasn't just about hitting military targets but also about breaking their spirit.

The bombardment blew out windows and walls of buildings that ring the square, which was piled high with debris and dust. Inside one building, chunks of plaster were scattered, and doors lay across hallways.

"People are under the ruins. We have pulled out bodies," said Yevhen Vasylenko, an emergency official.

Another Russian airstrike hit a residential area in the city of Zhytomyr. Ukraine's emergency services said Tuesday's strike killed at least two people, burned three homes and broke the windows in a nearby hospital. About 85 miles (140 kilometers) west of Kyiv, Zhytomyr is the home of the elite 95th Air Assault Brigade, which may have been the intended target.

Zelenskyy has mocked Russia's claim that it is going after only military targets, noting that 16 children were killed on Monday.

"Where are the children? What kind of military factories do they work at? What tanks are they going at?" Zelenskyy said.

Human Rights Watch said it documented a cluster bomb attack outside a hospital in Ukraine's east in recent days. Residents also reported the use of such weapons in Kharkiv and Kiyanka village. The Kremlin denied using cluster bombs.

Cluster bombs shoot smaller "bomblets" over a large area, many of which fail to explode until long after they've been dropped. If their use is confirmed, that would represent a new level of brutality in the war.

The first talks between Russia and Ukraine since the invasion were held Monday, but ended with only an agreement to talk again. On Tuesday, Zelenskyy said Russia should stop bombing first.

In his speech, Biden announced that the US was joining several other countries in closing its airspace to Russian planes. He also warned the country's oligarchs that the Department of Justice was assembling a task force to investigate any crimes they committed.

"We are joining with our European allies to find and seize your yachts, your luxury apartments, your private jets," he said. "We are coming for your ill-begotten gains."

Biden trumpeted the toll global measures had taken on the Russian economy already, including a stock market plunge and currency devaluation.

Moscow made new threats of escalation, days after raising the specter of nuclear war. A top Kremlin official warned that the West's "economic war" against Russia could turn into a "real one."

Inside Russia, a top radio station critical of the Kremlin was taken off the air after authorities threatened to shut it down over its coverage of the invasion. Among other things, the Kremlin is not allowing the fighting to be referred to as an "invasion" or "war."

Ukraine's Defense Ministry said it had evidence that Belarus, a Russian ally, is preparing to send troops into Ukraine. A ministry statement posted early Wednesday on Facebook said the Belarusian troops have been brought into combat readiness and are concentrated close to Ukraine's northern border. Belarusian President Alexander Lukashenko has said his country has no plans to join the fight.

A senior US defense official said that Russia's military progress -- including by the massive convoy -- has slowed, plagued by logistical and supply problems. Some Russian military columns have run out of gas and food, the official said, and morale has suffered as a result.

Overall, the Russian military has been stalled by fierce resistance on the ground and a surprising inability to completely dominate Ukraine's airspace.

The immense convoy, with vehicles packed together along narrow roads, would seemingly be "a big fat target" for Ukrainian forces, the senior Western intelligence official said on condition of anonymity. But it also showed Russia was comfortable that they wouldn't come attack by air, rocket or missile, the official said. (AP)
