North Korea's leader Kim Jong-Un will visit Russia for talks with Vladimir Putin this month, the Kremlin said Thursday, as tensions between Washington and Pyongyang reached fever pitch.
The Kremlin announced the talks just hours after North Korea launched an extraordinary attack on U.S. Secretary of State Mike Pompeo, demanding he be removed from negotiations over its banned nuclear programme.
Pyongyang also claimed Thursday to have tested a new kind of weapon with a "powerful warhead."
The Kim-Putin meeting will be the first between the two leaders, as Moscow seeks to play a role in another global flashpoint.

The Kremlin said Putin had invited Kim and that the meeting would take place "in the second half of April" but provided no further details.
Russia, South Korean and Japanese media had reported this week that preparations were underway for a summit in Russia's Far East.
Russia has relatively warm ties with Pyongyang and provides some food aid, and Putin has long expressed his readiness to meet with the regime leader.
Two senior U.S. officials -- presidential adviser Fiona Hill and special envoy for North Korea Stephen Biegun -- were in Moscow this week for talks with Russian officials.
Pyongyang and Washington have been at loggerheads since the collapse of a summit between Kim and President Donald Trump earlier this year.
Upping the ante in the diplomatic standoff, North Korea's foreign ministry on Thursday described Pompeo as "reckless" and immature and said it wanted him replaced.
"I am afraid that, if Pompeo engages in the talks again, the table will be lousy once again and the talks will become entangled," the official KCNA news agency quoted Kwon Jong Gun, director general of the ministry's Department of American Affairs, as saying.
"I wish our dialogue counterpart would be not Pompeo but ... [another] person who is more careful and mature in communicating with us."
Kwon said Kim had made clear that the U.S. attitude has to change and that Pompeo was standing in the way of a resumption of talks.
Since the beginning of the thaw in relations between the U.S. and North Korea, Pyongyang has been far happier to deal directly with Trump, who critics fear is too soft on the regime and is not sufficiently versed in diplomacy.
The U.S. president has made much of his personal relationship with Kim, musing on several occasions about their "love" for each other.
The February summit between Kim and Trump, the second between the two men, ended abruptly, with North Korea later protesting that the U.S. was being unreasonable.
North Korea has since said it is mulling options for its diplomacy with the U.S., and Kim said last week he was open to talks with Trump only if Washington came with the "proper attitude."
'Powerful Warhead' Tested
Adding to tensions, KCNA reported Thursday that Kim had supervised the test-firing of a new tactical weapon.
Wednesday's test was "conducted in various modes of firing at different targets" KCNA reported, adding that Kim described its development as one "of very weighty significance in increasing the combat power of the People's Army."
The report gave no details on the weapon.
South Korea had not detected anything on radar so it was unlikely to have been a missile, a military official told AFP.
A rapid diplomatic thaw on the Korean peninsula last year saw Kim meet not only Trump but also his South Korean counterpart Moon Jae-in and Chinese President Xi Jinping.
Little concrete progress has been achieved, however, and U.N. sanctions over the North's nuclear program remain in place.
Putin has previously expressed positions sympathetic to Kim's regime, saying last year that Pyongyang must be given guarantees in exchange for de-nuclearization.
The U.S. has accused Russia of trying to help North Korea evade some international sanctions, though Moscow denies this.
The last summit between a Russian and North Korean head of state came in 2011, when Kim's father Kim Jong Il travelled to Siberia to meet Dmitry Medvedev, then Russian president.
Kim Jong Il, who died shortly after the visit, told Medvedev his state was prepared to renounce nuclear testing.
