Russian President Vladimir Putin on Friday spoke of an "understanding" reached with US counterpart Donald Trump which he said could bring peace in Ukraine, without giving any details.

The leaders met for a highly anticipated summit in Alaska to discuss Russia's invasion of Ukraine and ways towards peace, but there was no apparent breakthrough deal.

"We hope that the understanding we have reached will... pave the way for peace in Ukraine," Putin said at a joint press conference with Trump after their talks.

He said Moscow expected "that Kyiv and the European capitals will perceive all this in a constructive manner and will not create any obstacles."

He also warned against "attempts to disrupt the emerging progress through provocation or behind-the-scenes intrigues."

The summit was held without Ukrainian President Volodymyr Zelenskyy who was not invited to talks, raising concerns in Europe that Moscow and Washington would try to decide Ukraine's fate behind its back.

Putin and Trump praised the meeting, with the Russian leader branding it as "constructive" and held in "mutually respectful atmosphere."

Speaking about Ukraine, Putin said Russia was "sincerely interested in putting an end" to the conflict in Ukraine but called for Russia's "legitimate concerns" to be taken into account.

"I have said more than once that for Russia, the events in Ukraine are associated with fundamental threats to our national security," Putin said.

He added that "a fair balance in the security sphere in Europe and in the world as a whole must be restored."

Russia has in the past repeatedly called on Ukraine to abandon its ambitions to join Nato and cede its eastern regions that Moscow claims to have annexed.

Ukraine has rejected the idea and called for any peace deal to include security guarantees to prevent Russia from attacking again.

Putin, landing in Alaska, stepped onto Western soil for the first time since he ordered the invasion of Ukraine in February 2022, a war that has killed tens of thousands of people.

On Friday he offered to host Trump in Moscow, extending the apparent invitation during their press conference.

"Next time in Moscow," Putin told Trump in English after the US president said he would "probably see you again very soon."

"Oh, that's an interesting one," Trump responded. "I'll get a little heat on that one, but I could see it possibly happening."

At least 34 people, including two babies were killed when a contraband fuel depot exploded into flames in southern Benin near the border with Nigeria on Saturday.

According to Beninese Interior Minister Alassane Seidou, “a serious fire occurred in the town of Seme Podji. Another 20 people were seriously wounded in the incident.”

"I can't really give you the cause of the fire, but there is a large gasoline warehouse here and cars, tricycles and motorcycles come from morning to evening,” he added.

Nigeria is a main oil and gas producer where fuel smuggling is very common along its borders, particularly when the government maintains a subsidy to keep fuel prices low.

The majority of the victims were burnt and they could not be not be identified.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
