Kim Jong Un's summit with Vladimir Putin at a cosmodrome in Russia's far east has finished
Putin says Kim will visit other sites in Russia before crossing back into North Korea
After dinner at the summit, the Russian leader toasted Kim's health and the two countries' friendship
Putin also says there are "possibilities" for military co-operation between the countries
Kim earlier said "we will always support the decisions of President Putin and... we will be together in the fight against imperialism"
The leaders did not discuss the risk of nuclear war, a Kremlin spokesman adds
Kim isn't the only one visiting Russia - Moscow has just announced that China's Foreign Minister Wang Yi will visit the Russian capital on Monday for talks with his counterpart Sergei Lavrov.
Just quickly back to the talks.
The North Korean leader has appeared to tell Putin that he supports Russia's invasion of Ukraine.
"Russia has risen to a sacred fight to protect its sovereignty and security against the hegemonic forces," Kim tells Putin.
"North Korea supports all Putin's decisions," he added.

Vladimir Putin and Kim Jong Un had been taking a look around Russia’s most modern spaceport, Vostochny Cosmodrome.
It’s an excursion that’s taken in launch pads and space rockets.
Space is a subject of huge interest to North Korea’s leader. His country has tried twice (and failed twice) to launch a military spy satellite.
Asked by a Russian reporter whether Moscow would help Pyongyang launch a satellite, President Putin replied: “That’s why we’ve come here. North Korea’s leader is very interested in rocket technology…”

"I'm so grateful you are paying such attention to our visit to Russia," Kim tells Putin.
"I'm sure we wil remain together in [the] fight against imperialism," he adds.
The Kremlin has released a 20-second clip of the two leaders sitting down for talks.
Putin says to Kim as the meeting begins: “Dear Chairman, I’m very glad to see and host you in Russia. This time, as we agreed, at the Vostochny Cosmodrome."
The last time they met was in 2019 at Vladivostok, the port city further south.

As the leaders were walking around the centre, Putin confirmed that they would discuss "all issues".
He also confirmed they would be discussing satellite tech - and that's why they are at this space base.
More pictures now are coming through of Putin and Kim's tour through the space centre.
Putin has told reporters that Kim is interested in developing North Korea's space programme and that Russia will assist with the North's satellites.

Basically, ammunition: Russia needs a lot of it in its war against Ukraine.
And North Korea, one of the most heavily militarised countries in the world, has plenty to spare.
The most likely weapons they'll offer Russia are bullets, shells, and even old missiles, Kim Dong-yup, a professor at the University of North Korean Studies, told the BBC.
The country has tens of millions of artillery shells and rockets, according to some estimates. Analysts believe there could be a healthy stockpile because the North has not fought a war since the Korean War ended in 1953.
Prof Kim said handing these older munitions to Russia will not dampen the North's defence capabilities - at a recent military parade, their army appeared to be armed with new weapons.
Pyongyang's firearms are also largely based on Soviet weapons systems. That makes North Korean munitions, to a large degree, compatible with Russia's arsenal.
Putin says he is meeting Kim at the Vostochny Cosmodrome because the North Korean leader "shows great interest in rocket engineering".
That's certainly one way of describing North Korea's banned missile test launches and nuclear weapons development over the past years.
"They are also trying to develop their space programme," Putin was quoted by Russian news agencies saying.
North Korea has been keenly developing its satellite programme although both attempts to put a spy satellite into space this year ended in failure.
The first attempt in May saw the satellite crash into the sea shortly after taking off. The second attempt last month failed during the third stage of its flight.
Pyongyang's space agency has said it will try again in October.
Analysts say a spy satellite would be a coveted prize for Kim as it would let him monitor incoming attacks and plot his own more accurately.

Asked if he and Kim would discuss weapons supplies or military-technical co-operation, Putin replied: "We will discuss all the topics".
Putin appears to have been answering some questions from reporters at the space centre.
Asked if Russia will help North Korea build satellites, Putin said: "This is why we've come to Vostochny Cosmodrome," Russian news media RIA reports.
North Korea has failed twice to place spy satellites into orbit, and it's been heavily speculated that it will ask Russia for help with its space programme.
Asked by reporters if an arms deal between the two countries is on the agenda, a Kremlin spokesman said Pyongyang and Moscow cooperate in "sensitive areas" which should not be made public.
The two sanctioned regimes are expected to strike a deal which exchanges weapons for humanitarian aid.
Putin is now showing Kim around the facilities at Vostochny Cosmodrome, according to Russian TV.
PrimaMedia reported that Kim will be shown how the Angara launch vehicle is being assembled.
He and Putin will also inspect the launch complex for the Soyuz-2 launch vehicle, after which they will hold negotiations.
The spaceport was built in 2016, about a decade after it was commissioned by Putin. He said at the time that he wanted to rely less on other countries for its space exploration programme.
"I am glad to see you," said Putin to Kim as he welcomed the leader of North Korea to Russia's advanced space site.
"This is our new cosmodrome," Putin added, introducing him to the Vostochny space centre launched in 2016.
Kim then thanked Putin for the invitation, according to the video published on the Kremlin's Telegram channel.

"Thank you for inviting us during your busy schedule," said Kim to Putin as they shook hands and greet each other.
That's from the video we've seen that was published on the Kremlin's official Telegram channel. It's the first pictures we have of the two leaders meeting.
