London, Feb 6 : Russian Prime Minister Vladimir Putin is such huge fan of Abba that he actually called the band to his homeland for a private concert.

Putin was seen dancing away at the band's Honey Honey song along with Kremlin officials, as Kalashnikov-wielding guards patrolled the building.

"I got a phone call before Christmas. The voice on the end of the phone said, ''Kremlin... Russia... Moscow... we want your band''," the Telegraph quoted Bjorn Again''s founder, Rod Stephens, as saying.

Brussels  - The European Union warned Russia Thursday not to go ahead with its plans to build up a military presence in Georgia's breakaway regions of South Ossetia and Abkhazia, saying they would jeopardize stability and security.

Moscow - Bulgarian President Georgi Parvanov meeting in Moscow with his Russian counterpart Dmitry Medvedev, on Thursday called for more urgency in building alternative pipeline routes to carry Russian gas to Europe bypassing Ukraine.

Wiesbaden, Germany - Representatives of six major powers met Wednesday to discuss how they could resolve the stand-off with Iran over its controversial nuclear programme.

Stubb referred to a variety of pipeline projects designed to deliver energy supplies to Europe from Russia and the Middle East.
