A terrorist attack was carried out at the Crocus City Hall music venue in the city of Krasnogorsk near Moscow on Friday evening. Unidentified gunmen armed with assault rifles went on a shooting spree. An explosion rocked the building, starting a fire.
JUNE 6: Ben Wallace said the M270 multiple-launch rocket system will help Ukraine defend itself against Russia.
The UK government has not confirmed how many weapons will be sent, but the BBC understands it will be three initially.
The decision was co-ordinated with the US, which announced last week it was also supplying a rocket system.
The move by the US has already angered Moscow and on Sunday Russian President Vladimir Putin threatened to expand the list of targets Russia will attack in Ukraine if Western countries send long-range weapons to Kyiv.
The UK government said the Ukrainian military will be trained in how to use the launchers in the UK in the coming weeks.
Announcing the move, Mr Wallace said the UK was taking a leading role in supplying Ukrainian troops with the "vital weapons they need to defend their country from unprovoked invasion".
He said: "As Russia's tactics change, so must our support to Ukraine.
"These highly capable multiple-launch rocket systems will enable our Ukrainian friends to better protect themselves against the brutal use of long-range artillery, which Putin's forces have used indiscriminately to flatten cities."
Britain and America have led the way in supplying weapons to Ukraine, but giving it advanced long range rockets marks a significant shift, said the BBC's defence correspondent Jonathan Beale.
It is also a recognition that Ukraine is struggling to compete against Russia's vast artillery arsenal, he added.
The UK's multiple launch rocket system can fire 12 surface-to-surface missiles within a minute and can strike targets within 50 miles (80km) with pinpoint accuracy - far further than the artillery Ukraine currently possesses.
It is similar to the system the US is sending, the M142 High Mobility Artillery Rocket System (HIMARS).
Last week Washington said it would supply four HIMARS multiple rocket launchers to Ukraine - following receipt of guarantees they would be used for defensive purposes only and not to strike targets inside Russia.
In an interview on Russian state TV on Sunday, Mr Putin said: "In general, all this fuss about additional arms supplies, in my opinion, has only one goal - to drag out the armed conflict as long as possible."
The Russian leader said what the US was supplying was "nothing new".
But he warned against sending missiles with longer ranges: "If they are supplied, we will draw appropriate conclusions from this and use our weapons, of which we have enough, to strike at those targets that we are not striking yet."
The warning came as explosions shook parts of Kyiv on Sunday in the first assault on the capital city for weeks, while fierce fighting for control of key towns and cities in the eastern Donbas region continues.
Russia refocused its military efforts on the Donbas at the end of March after pulling back from the Kyiv region.
Some of the fiercest fighting is currently in the eastern city of Severodonetsk. Capturing the city would deliver the Luhansk region to Russian forces and their local separatist allies, who also control much of neighbouring Donetsk. The two regions form the heavily industrial Donbas.
On Sunday, Ukraine's president, Volodymyr Zelensky, said he had visited front-line troops in the eastern Donbas region to the city of Lysychansk and the town of Soledar.
Britain and the US have are among the leading nations giving arms to support Ukraine since Russia invaded in February.
The UK has also delivered more than 5,000 next generation light anti-tank weapons - known as Nlaw - which analysts believe have been critical to Ukraine driving back Russian ground assaults since the war began.
Other weapon systems delivered by the government include short-range Brimstone 1 missiles, Mastiff armoured vehicles and Starstreak missile air defence systems - with the overall military support to Ukraine costing £750m so far, the government said.
Several other countries have pledged to send advanced weapons to Ukraine. Germany has promised to send its most modern air defence system - the Iris-T - to enable Ukraine to shield an entire city from Russian air attacks.
Support for war crimes investigation
Meanwhile, a specialist team of lawyers and police officers will be offered to assist the chief prosecutor investigating alleged Russian war crimes in Ukraine, the Justice Secretary Dominic Raab announced on Monday.
The offer will include a Metropolitan Police officer stationed in the International Criminal Court in The Hague, in the Netherlands - who will provide the ICC's prosecutor Karim Khan with greater access to British police and military expertise.
On top of this, seven lawyers experienced in international criminal law will be offered to help uncover evidence of war crimes committed in Ukraine and prosecute those responsible.
The ICC has already begun an investigation that may target senior Russian officials thought to be responsible for war crimes, crimes against humanity or genocide.
Atrocities and mass graves have been reported in towns and cities around Ukraine previously occupied by Russian forces - who withdrew from around the Kyiv and other areas they previously occupied to focus their offensive in the east.
Civilian massacres have been discovered in places like Bucha, a town near the Ukrainian capital, with people found dead in the street, having been allegedly bound, gagged and executed by retreating Russian soldiers.
Ukraine has so far reported 15,000 suspected war crimes, including Ukrainian women alleging being raped by Russian troops.
Some 600 suspects have been identified and 80 prosecutions have begun, with one tank commander already sentenced to life in prison in May, after being found guilty by a Kyiv court of shooting a 62-year-old civilian in the back.
MAY 23: Captured soldier Sgt Vadim Shishimarin was convicted of killing Oleksandr Shelipov, 62, in the north-eastern village of Chupakhivka on 28 February.
He admitted shooting Mr Shelipov but said he had been acting on orders and asked forgiveness of his widow.
Multiple other alleged war crimes are being investigated by Ukraine.
Moscow has denied its troops targeted civilians during the invasion while Ukraine says more than 11,000 crimes may have occurred.
This trial in the Ukrainian capital Kyiv is being seen as Ukraine's chance to prove, beyond doubt, that a Russian soldier killed a civilian with no regard for the rules of war.
Moscow said earlier on Monday that it was concerned at the fate of the Russian soldier and would look at options to defend him.
Kremlin spokesperson Dmitry Peskov noted, however, that Russia did "not have the capacity to protect his interests in person". Russia's embassy in Kyiv is currently closed.
Shishimarin, wearing a blue and grey hooded sweatshirt, watched proceedings silently from a reinforced glass box in the courtroom and showed no emotion as the verdict was read out, Reuters news agency reports.
At the time of the killing Shishimarin, 21, and other soldiers were travelling in a car they had seized after their convoy came under attack and they became separated from their unit.
When they spotted Mr Shelipov he was speaking on his phone, Shishimarin told the court. He says he was told to shoot him with an assault rifle.
His defence lawyer told the court on Friday that Shishimarin had only fired after twice refusing to carry out the order to shoot and that only one out of three to four rounds had hit the target.
He said Shishimarin had fired the rounds out of fear for his own safety and he questioned whether the defendant had intended to kill.
In one dramatic moment during the trial, the victim's widow Kateryna Shelipova confronted Shishimarin. "Tell me please, why did you [Russians] come here? To protect us?" she asked, citing Russian President Vladimir Putin's justification for the invasion of Ukraine.
"Protect us from whom? Did you protect me from my husband, whom you killed?"
The soldier had no answer to that. Asking forgiveness of the widow earlier, he said: "But I understand you won't be able to forgive me."
Mrs Shelipova told the BBC: "I feel very sorry for him but for a crime like that - I can't forgive him."

Gunmen killed at least seven people and wounded 20 on Friday in an assault on an Islamic seminary in a Rohingya refugee camp in Bangladesh, heightening tensions in the settlements after the recent shooting of a community leader, a media report said.
WASHINGTON, Feb 22: Students galvanized by the deadly mass shooting at a Florida high school confronted lawmakers on Wednesday with demands to restrict sales of assault rifles, while President Donald Trump suggested arming teachers as a way to stop more U.S. rampages.
FLORIDA, Feb 16: The 19-year-old man accused of shooting 17 people to death at a Florida high school legally purchased the assault rifle used in the killings and may have foreshadowed the attack in a social media comment investigated by the FBI last year, authorities said on Thursday.
