Portugal Colonial - Ukraine marks 'Day of Unity' as NATO warns on Russia pullback

Ukraine's President Volodymyr Zelensky watched troops training with some of their new Western-supplied anti-tank weapons on a range near Rivne, west of the capital.

The demonstration of Ukrainian firepower contrasted with images on Russian state media that were said to show Moscow's forces bringing an end to a major exercise in occupied Crimea.

In Rivne, a row of vehicles was destroyed by simultaneous missile test strikes and armoured vehicles manoeuvred and fired on the yellowing moorland, while in Kyiv hundreds of civilians marched in a stadium with an enormous national banner.

The "Day of Unity" displays came as the Kremlin called for "serious negotiations" with Washington, and European leaders pushed hard for a diplomatic resolution to the crisis.

NATO chief Jens Stoltenberg, hosting the alliance's defence ministers in Brussels, dismissed suggestions that the threat on the border had diminished.

"It remains to be seen whether there is a Russian withdrawal," he said.

"We are of course monitoring very closely what Russia does in and around Ukraine. What we see is that they have increased the number of troops and more troops are on their way."

- 'Signals give us hope' -

Russia's huge build-up of troops, missiles and warships around Ukraine -- which US intelligence warns could turn quickly into an invasion -- has been called Europe's worst security crisis since the Cold War.

Russian President Vladimir Putin has demanded Ukraine be forbidden from pursuing its ambition to join NATO and wants to redraw the security map of eastern Europe, rolling back Western influence.

But, backed by a threat of crippling US and EU economic sanctions, Western leaders have launched a drive to seek a negotiated settlement, and Moscow has signalled it will start to pull forces back.

In the latest such move, on Wednesday the Russian defence ministry said military drills in Crimea -- a Ukrainian region Moscow annexed in 2014 -- had ended and that troops were returning to their garrisons.

Washington has demanded more verifiable evidence of de-escalation, but US President Joe Biden on Tuesday nevertheless vowed to push for a diplomatic solution.

Kremlin spokesman Dmitry Peskov told reporters: "It is positive that the US president is also noting his readiness to start serious negotiations."

German Defence Minister Christine Lambrecht, arriving at the NATO talks, said reports of a partial Russian pullback "are signals that at least give us hope. But it is important to observe closely whether these words are followed by deeds."

Zelensky has downplayed threats of an immediate Russian invasion, but is attempting to rally his people with "Day of Unity" celebrations under Ukraine's blue and gold banner.

On Wednesday, after the Rivne drills, he was to visit Mariupol, a frontline port city near a breakaway region held by Russian-backed separatists.

In a video message, the 44-year-old former television actor turned leader said the flag would fly across the country and that the national anthem "Ukraine has not yet died" would be sung.

"Great people of great Ukraine! This day is ours," he declared.

The European Union ambassador to Ukraine, Matti Maasikas, along with the German, Estonian, Polish and Spanish envoys were headed to Mariupol with the president in solidarity.

Maasikas also said that he had raised the Ukrainian flag alongside the EU one at his embassy, adding: "Not sure it's fully according to the rules, but these are extraordinary times."

In Kyiv, the capital's deputy mayor Valentyn Mondryivsky said headteachers have been given guidance on "emergency situations" and that bomb shelters would be available at all schools.

- Rich return -

In another sign of Ukraine's most powerful figures coming together, some wealthy business leaders who had been urged to come back to the country announced their return.

Ukraine's richest man, 55-year-old billionaire industrialist Rinat Akmetov, who was born in Donetsk in an area now held by separatists, was in Mariupol.

"We continue to build, we continue to invest. This year, Metinvest will invest $1 billion in new production," he said, referring to his company, promising to boost salaries and support a local university.

On Tuesday, Ukraine said the websites of the country's defence ministry and armed forces as well as two banks had been hit by a cyberattack of the kind that US intelligence fears would precede a Russian attack.

"It cannot be excluded that the aggressor is resorting to dirty tricks," Ukraine's communications watchdog said, in reference to Russia.
