This was CNBC's live blog tracking developments on the war in Ukraine.
Russia's Dmitry Medvedev said on Friday that the Kremlin isn't bluffing over its threats to use tactical nuclear weapons against Ukraine.
In a Google-translated post published on his official Telegram channel, Russia's former president said Moscow's use of tactical nuclear weapons can be "miscalculated" but that the Kremlin's position on the potential deployment of these weapons was not "not intimidation or nuclear bluff."
His comments come shortly after reports said U.S. President Joe Biden had quietly given permission to Ukraine to allow its forces use U.S. weapons inside Russia. The decision only applies to counter-fire purposes in the area around Ukraine's northeastern region of Kharkiv.

U.S. Secretary of State Antony Blinken on Friday confirmed that the U.S. President Joe Biden approved Ukraine's usage of weapons supplied by the U.S. within Russia. This only applies to Russian targets that are attacking Ukraine's Kharkiv region.

"And that went right to the President, and as you've heard, he's approved use of our weapons for that purpose. Going forward, we'll continue to do what we've been doing, which is as necessary adapt and adjust," he said.

Ukraine signs security deals with Sweden, Norway, Iceland
Ukraine on Friday signed security agreements with Sweden, Norway and Iceland.
The agreements all cover additional financial and other forms of support for Ukraine, statements published on Zelenskyy's website outlined.
Ukrainian President Volodymyr Zelenskyy earlier in the day said on social media platform X that he was in Sweden for the third Ukraine-Northern Europe summit and was meeting various regional leaders.
Sweden is set to provide military assistance worth 6.5 billion euro ($7.13 billion) between 2024 and 2026, as well as air defense systems, specialized aircraft used for surveillance, artillery and other military support. Iceland will support Ukraine financially in the years to come and help procure, finance and deliver military supplies and equipment to Kyiv. Finally, Norway will also boost its monetary support and help develop Ukraine's modern combat aircraft and maritime capabilities.
The three new agreements take the total number of security deals Ukraine has with Western countries to 15. That includes arrangements with the other two Nordic countries, Denmark and Finland, which also participated at Friday's summit.

Finland, Estonia call for additional defense spending
Russian border countries Finland and Estonia on Friday called for a boost to defense spending to protect nations against aggression from their neighbor, Reuters reported.
At the Shangria-La Dialogue security summit in Singapore, Estonian Defence Minister Hanno Pevkur said that the country was advocating for the NATO coalition to increase the amount its members should spend on defence from 2% to 2.5% of their gross domestic product ahead of the NATO summit in July.
"We clearly see there are shortages and challenges for the NATO countries in order to be ready to defend our alliance and this is why we need to increase rapidly our defence spending," he said.
Meanwhile, Finnish Deputy Defense Minister Esa Pulkkinen said decisions around command and control arrangements that will be made at the NATO summer reunion would be "of crucial importance."
"We saw that Russia is capable and willing to wage a full-scale war on its neighbour," Pulkkinen said. "It became clear that no small state could cope by themselves when brutally attacked by a much bigger enemy."

NATO chief dismisses Russian warnings of escalation after lifting of arms restrictions
NATO chief Jens Stoltenberg on Friday dismissed warnings by Russian President Vladimir Putin that allowing Kyiv to use Western weapons for strikes inside Russian territory might lead to an escalation.
Speaking on the sidelines of a NATO foreign ministers' meeting in Prague, Stoltenberg said the alliance had heard such warnings many times before.
"This is nothing new. It has (...) been the case for a long time that every time NATO allies are providing support to Ukraine, President Putin is trying to threaten us to not do that," he told reporters.
"And an escalation – well, Russia has escalated by invading another country."
Putin on Tuesday warned NATO members against allowing Ukraine to fire their weapons into Russia and raised anew a risk of nuclear war after several allies lifted restrictions imposed on the use of weapons donated to Kyiv.

Russian court extends detention of Russian-U.S. journalist Kurmasheva
A Russian court on Friday extended until Aug.5 the pre-trial detention of journalist Alsu Kurmasheva who hold Russian and United States citizenships, a Reuters correspondent reported from the courtroom in the city of Kazan.
Kurmasheva is a Prague-based journalist for Radio Free Europe/Radio Liberty (RFE/RL), which is funded by the U.S. Congress and designated by Russia as a foreign agent, meaning it gets foreign funding for activity deemed to be political.
Her employer says her detention on charges of violating Russia's law on foreign agents is unjust and politically motivated.

EU's 14th sanctions package must target circumvention, energy exports, Zelenskyy advisor says
The European Union's upcoming 14th sanctions package against Russia must do more to choke off energy exports and clamp down on circumvention by third parties, an advisor to the office of Ukraine President Volodymyr Zelenskyy told CNBC.
Vladyslav Vlasiuk said it was also vital to tighten export controls on critical technologies used within Moscow's military equipment. However, he noted that EU states would need to work more cohesively for sanctions to stand a chance of crossing the line by the end of next month as planned.
"The most critical aspect of the 14th sanctions package is its adoption by the end of June, but some member states currently pose a challenge to this," Vlasiuk said via email Thursday.
The EU's special envoy for the implementation of sanctions, David O'Sullivan, was in Kyiv Thursday to discuss the latest sanctions package amid ongoing pushback from member states such as Hungary. Among the proposed measures is a ban on Russian liquified natural gas (LNG) exports and a crackdown on sanctions circumvention via countries including Kremlin ally Belarus.
Nataliia Shapoval, a member of the Yermak-McFaul International Working Group on Russian Sanctions, a think tank which advises on EU sanctions, said the LNG proposals were an attempt to restrict both Russia's current and future energy revenues.
"LNG is the leverage that Russia still maintains," Shapoval said over the phone.
Russia said Wednesday that such a ban would hurt the EU more than it would Russia, and that some LNG supplies were already being redirected to China and India. Shapoval noted, however, that gas supplies were much more difficult to direct without European infrastructure than, for example, oil.
She added that the EU was currently playing a "cat and mouse game" to determine which critical components were propping up Moscow's military might and should therefore be banned.

NATO chief says 'time has come' to re-consider restrictions on weapons sent to Ukraine
NATO chief Jens Stoltenberg on Thursday said it was time for members of the military alliance to re-consider restrictions placed on weapons they send to Ukraine, Reuters reported.
Allies were sending various types of limitary support to Ukraine, and any restrictions on the support are national decisions, he said ahead of a NATO foreign ministers' meeting.
"But I think that in light of how this war has evolved ... the time has come to consider some of these restrictions, to enable the Ukrainians to really to defend themselves."
Opinions on restrictions on weapons and military supplies are split among Ukraine's allies. Some including the U.K. have said Ukraine could use weapons it supplied for strikes on Russian soil, while Italy has said weapons it supplied should only be used within Ukraine.

Sri Lanka tightens controls to stop men being duped into Ukraine fighting
Sri Lanka will tighten controls to try to stop its men being lured to Russia to fight in Ukraine with often false promises of salaries and benefits, a minister said on Thursday.
Colombo will also send a delegation to Moscow in June to bring back dozens of Sri Lankans already fighting in the front line who want to come home, some of them wounded, State Minister for Foreign Affairs Tharaka Balasuriya told reporters.
Countries across the region, including India and Nepal, have raised the alarm about their men being persuaded to travel to fight for Russia in Ukraine with offers of salaries, visas and sometimes university places.
Russia's ambassador to Sri Lanka, Levan S. Dzhagaryan, told the press conference on Thursday his embassy would cooperate with the efforts to stop Sri Lankans travelling illegally to Russia. He said his government was not involved in the recruitment offers.
Under the new controls, men will have to produce a "no-objection" document from the Sri Lankan defence ministry when they apply for a tourist visa to Russia, Tharaka Balasuriya told reporters.
