G7 \\\'to intensify Russia sanctions\\\'

The G7 group of economic powers has agreed to intensify sanctions on Russia over its actions in Ukraine. A G7 statement gave no detail of the sanctions, but US officials said they could announce measures by Monday. The West accuses Russia of leading a secession rebellion in Ukraine's east, months after it annexed Crimea. Moscow denies the allegations. Meanwhile, negotiators are trying to secure the release of international observers seized by pro-Russia gunmen. Forces in the city of Sloviansk are still holding the eight European military observers and several Ukrainian army personnel who they seized on Friday and accuse of espionage, according to BBC.
