In its latest intelligence update, external, the UK's Ministry of Defence (MOD) says that in the first three months of the war, Russia is likely to have suffered a similar death toll to that seen by the Soviet Union during its nine-year war in Afghanistan.

The high casualty rate - seen in the Donbas offensive - can be explained by a combination of poor low-level tactics, limited air cover, lack of flexibility and "a command approach which is prepared to reinforce failure".

The MoD predicts those casualties, as they continue to rise, will become more apparent to the Russian public, and "public dissatisfaction with the war and a willingness to voice it may grow".

It is a pointed reference. The Soviet Union lost at least 15,000 soldiers in the Afghan conflict trying to prop up a communist government. The war became a bloody stalemate, and is viewed as a factor in the collapse of the Soviet Union.

After winning the English Premier League title for the fourth time with his club Manchester City, Ukrainian footballer Oleksandr Zinchenko has said he found it hard to even think about football after Russia invaded Ukraine in February.

Speaking to Sky Sports after draping the Ukrainian flag around the Premier League trophy, an emotional Zinchenko called it an unforgettable moment.

"I'm so proud to be Ukrainian," he said. "I would love to one day bring this title to Ukraine, for all Ukrainian people, because they deserve it."

Zinchenko said the time since the invasion began was the "toughest period in my life".

In an interview with BBC Sport's Gary Lineker soon after the start of the war, the Manchester City defender said he could not count the number of times he had cried since Russia's invasion began.

Ukraine has extended martial law for three months until 23 August.

President Volodymyr Zelensky first signed the decree, along with a general military mobilisation call, on 24 February and since then has extended it for a month on two occasions.

On Sunday, Ukraine's parliament voted by an absolute majority for a third extension as Russia continues to focus its offensive on the eastern Donbas region.

Zelensky's representative at the Constitutional Court, Fedir Venislavskyy, said the decision to extend it for 90 days this time is because a "counter-offensive takes more time than defence".

Under martial law, Ukrainian men aged 18-60 are banned from leaving the country unless they have special exemptions.

Russian troops have been trying to break through defence lines of Ukrainian forces and reach the administrative borders of the eastern Luhansk region, Ukraine's military says in its latest report on Monday morning.

The Russians have been focusing their efforts towards the city of Severodonetsk, the General Staff of Ukraine's Armed Forces says.

It adds that "the enemy" has intensified the use of its aircraft in order to destroy Ukraine's critical infrastructure in the area of active combat operations.

Ukraine's forces have repelled 11 enemy attacks in the east over the past 24 hours, the report adds.

The BBC is not able to verify the contents of the report.

The Polish president has delivered a message of strong support for Ukraine during the first address in person by a foreign leader to the parliament in Kyiv since the Russian invasion began.

During his speech on Sunday, Andrzej Duda thanked Ukraine for defending Europe against what he called “Russian imperialism”.

“The free world”, he said, “has the face of Ukraine.” Duda said recent calls for Kyiv to negotiate with President Putin, and even give in to some of his demands, were disturbing. No decisions about your future will be made without you, he said.

Poland has been one of Ukraine’s staunchest supporters, taking in millions of refugees fleeing the fighting and sending tanks and rocket launchers to the Ukrainian military.

Duda, who received a standing ovation after his speech, said Poland would do everything it could to help Ukraine join the European Union.

"The number of people forced to flee conflict, violence, human rights violations and persecution has now crossed the staggering milestone of 100 million for the first time on record, propelled by the war in Ukraine and other deadly conflicts," the UN High Commissioner for Refugees says.

In a statement, UNHCR chief Filippo Grandi says this is "a stark figure - sobering and alarming in equal measure., externalIt’s a record that should never have been set.

"This must serve as a wake-up call to resolve and prevent destructive conflicts, end persecution, and address the underlying causes that force innocent people to flee their homes.”

The UNHCR says the war in Ukraine has displaced eight million within the country, and more than six million people have fled abroad.

Last year, the UN tally of those displaced rose to 90 million because of violence and conflict in countries including Ethiopia, Burkina Faso, Myanmar, Nigeria, Afghanistan and the Democratic Republic of Congo.
