Ukraine-Russia war latest: Moscow warns US of 'fatal consequences'; Russia suffers more than 1,000 casualties in 24 hours, Ukraine claims

Around 1.5 million men have registered for conscription in Ukraine, the defence ministry has said.

According to a video posted to the ministry's YouTube channel, the majority of the updates were carried out using the new Reserve+ online app.

After the new law on mobilisation came into force on 18 May, military-aged men were given 60 days to update their personal data so that the state could locate them.

In addition to using the app, Ukrainians can update their data in person at public service centres or enlistment offices.

The ministry added that 14,000 men living abroad across 124 countries had updated their credentials. 

Ahead of the 80th anniversary of D-Day, Britain's defence chief Admiral Sir Tony Radakin spoke about the comparisons made between the Second World War and the conflict in Ukraine.

He told Sky News he is confident we are not heading towards another world war and has every faith Ukraine would prevail in its fight.

Admiral Radakin added that by the end of June, 500,000 Russians would have died or been injured in the conflict.

Kazan's airport has imposed temporary flight restrictions for safety reasons today, Russia's aviation watchdog has said.

This is usually done in expectation of Ukrainian drone attacks.

Kazan is the capital of the Russian Republic of Tatarstan and is located about 500 miles east of Moscow.

The region has been repeatedly attacked by drones in recent  months, an indication that Ukraine has dramatically improved its ability to strike deep within Russian territory.

Ukraine has claimed the Russian military has suffered 1,270 casualties in the past 24 hours, the Ukrainian general staff said on Monday. 

If that toll, released by the Ukrainian general staff this morning, is correct, it would be one of the highest daily Russian casualty figures since the war began. 

Kyiv has regularly claimed that Moscow's forces have lost more than 1,000 men a day since Russia launched a new offensive in the Kharkiv region last month. 

The Kharkiv region, which borders Russia, and Kharkiv city, the administrative centre of the region, have been battered nearly daily, since the attacks intensified.

The news comes on the heels of last week's decision by President Joe Biden to approve the use of US supplied weapons to hit targets inside Russia that were involved in attacks on Ukraine's Kharkiv region. 

Volodymyr Zelenskyy has said Donald Trump risks being a "loser president" if he retakes the White House and imposes a bad peace deal on Ukraine.

The Ukrainian president said he had "no strategy yet" for what to do if Trump wins in November and that Boris Johnson had approached the Republican on his behalf, according to The Guardian.

He said if Trump were re-elected, the Republican could impose a crushing defeat on Ukraine, should he so chose. 

It's widely thought Trump may end US military support for Ukraine if he gets into the White House.

"Ukraine, barehanded, without weapons, will not be able to fight a multimillion [Russian] army," Mr Zelenskyy told the paper.

"Does he want to become a loser president?" he said.

"A ceasefire is a trap," he added, saying that after a break in hostilities Vladimir Putin would "go further" and make Trump look "very weak" in the eyes of the world.

Donald Trump has previously claimed he could "end the war in 24 hours".

We're getting more warnings from Russia to the US now. 

The foreign ministry told the US not to make any "mistakes that may have fatal consequences" with regards to allowing Ukraine to strike targets on Russian soil, the Interfax news agency reported.

It comes after the foreign ministry earlier warned that Ukraine using Patriot air defence systems in Russia would escalate the conflict.

Beijing has hit back at Volodymyr Zelenskyy after he accused the country of helping Russia disrupt a global peace conference in Switzerland.

China has said it would not be attending the summit because Russia would not be taking part alongside Ukraine.

The Chinese foreign ministry said it believes all efforts should be recognised by all in supporting peace measures around the Russia-Ukraine war.

Beijing has never "fanned fire or fuelled the flames", said ministry spokesperson Mao Ning, addressing a question on the peace summit. 

She added that there was "no situation of China exerting pressure on other countries". 

In the same press conference, Ms Mao also said China wanted to "deepen oil and gas cooperation with Russia".

Yesterday, speaking at the Shangri-La defence forum in Singapore, Asia's premier security conference, Mr Zelenskyy said China is pressuring other countries and their leaders not to attend the Summit on Peace in Ukraine, scheduled for 15-16 June.

"Russia, using Chinese influence in the region, using Chinese diplomats also, does everything to disrupt the peace summit," he said.

"Regrettably this is unfortunate that such a big independent powerful country as China is an instrument in the hands of Putin."

Russia has said discussions over allowing Ukraine to use Patriot MIM-104 air defence systems over Russian territory show the West is on a "path of escalation".

The state-run TASS news agency cited Moscow's foreign ministry as making the remarks today. 

"Russia will take all measures to thwart such threats," the ministry added.

In April, the Pentagon said it would "rush" Patriot air defence missiles and artillery ammunition to Ukraine as part of its new $6bn military aid package.

However, Patriot systems for launching the missiles will not be sent, Defence Secretary Lloyd Austin said at the time.

Volodymyr Zelenskyy has been forthright in saying the weapons are needed urgently and their absence is costing Ukrainian lives.

"Patriot" stands for "Phased Array Tracking Radar to Intercept on Target" and is a long-range, all-altitude, all-weather air defence system designed to counter tactical ballistic missiles, cruise missiles and advanced aircraft. 

The American-made missiles are produced by Raytheon in Massachusetts and Lockheed Martin Missiles and Fire Control in Florida.

The system is used by the US and some of its allies, including Germany, Greece, Israel, Japan, Kuwait, the Netherlands, Saudi Arabia, South Korea, Poland, Sweden, Qatar, the United Arab Emirates, Romania, Spain, and Taiwan.

Hungarian foreign minister Peter Szijjarto has said his country has not yet decided whether to join a global peace summit aimed at helping to end the war in Ukraine. 

He said that while he respected efforts by Switzerland to achieve peace, he doubted whether the summit made sense if "there aren't both parties to the war" present. 

Russia will not attend the summit, which is being held later this month. 

Hungary has repeatedly opposed Ukraine's accession to NATO and the EU, sanctions on Russia, undermined Western aid efforts for Ukraine, and maintained close relations with Moscow throughout the full-scale war.

In mid-May, it vetoed a Council of Europe resolution to officially recognise and support Volodymyr Zelenskyy's 10-point peace formula. 

"If both sides of the war are not represented, I think it is a legitimate question whether the whole summit makes sense in terms of the ultimate goal, which is to seek peace," Mr Szijjarto said.

"We [Hungary] believe that the peace summit has real meaning and gives the greatest hope for peace if both sides are at the table."

Volodymyr Zelenskyy is making a surprise appearance in the Philippines today, thanking it for its participation in a high-level peace summit later this month. 

In their first in-person meeting in Manila, the Ukrainian president thanked President Ferdinand Marcos Jr for his "clear position" on Russia's "occupation of our territories". 

"I'm happy to hear today from you that you participate (in) our basic steps to the peace," Mr Zelenskyy told his Philippine counterpart during their bilateral meeting, speaking in English.

He also announced that Ukraine would open an embassy in Manila this year.
