US Central Intelligence Agency director William Burns met the head of Russia's powerful Security Council for talks in Moscow on Tuesday, the council's press service said.

Burns and Security Council Secretary Nikolai Patrushev discussed "Russian-American relations", it said in a terse statement.

Burns' visit to Moscow was not previously announced and the Security Council released no further details.

There was no immediate comment from the US embassy in Moscow or officials in Washington.

The meeting comes with Russia's ties with the West at their lowest levels in years, strained by a wide range of disagreements.

Western nations have imposed a series of sanctions on Russia over its 2014 annexation of Crimea, alleged election interference, cyberattacks and the poisoning of Kremlin critic Alexei Navalny.

But US officials have said they are looking for cooperation with Moscow on specific issues, including strategic arms reductions, the Iran nuclear talks and cracking down on ransomware and other cyberattacks.

US President Joe Biden and Russian counterpart Vladimir Putin met for their first summit in June and agreed to keep communications channels open.

Russian and US diplomats have since held closed-door talks in Geneva on arms control and the State Department's Under Secretary for Political Affairs Victoria Nuland was in Moscow for talks last month.

Burns, a veteran diplomat who was the US ambassador to Russia in 2005-2008, became CIA director in March.
