British Foreign Secretary William Hague said on Saturday that Russian action was a "potentially grave threat" to Ukraine's sovereignty, independence and territorial integrity, Reuters reported. Hague said he had spoken to Russian Foreign Minister Sergei Lavrov to urge steps to calm the situation, and had summoned the Russian ambassador to register Britain's concern. "I am deeply concerned at the escalation of tensions in Ukraine, and the decision of the Russian parliament to authorise military action on Ukrainian soil against the wishes of the Ukrainian Government," Hague said in a statement. "We condemn any act of aggression against Ukraine." -- SPA 21:01 LOCAL TIME 18:01 GMT تغريد
