DHAKA: Russia is on a ‘dark path’ to isolation over its actions in Ukraine and the United States will respond to any aggression against Nato allies.

US vice president Joe Biden said on Wednesday, reports The Straits Times.

Biden made the comments during a trip to Lithuania to reassure Baltic allies worried about what an emboldened Russia might mean for their nations.

Lithuania, along with fellow Baltic nations of Latvia and Estonia, are Nato members.
