Russian soldiers sit atop their tank during military exercises in the southern Russia’s Volgograd region, on April 3, 2014. Russian troops deployed close to the Ukrainian border will return to base after completing their exercises, Foreign Minister Sergei Lavrov said yesterday. NATO said earlier this week it had stepped back from a floated idea to reinforce the alliance’s military presence in countries bordering Russia, preferring for now to suspend cooperation with Moscow and give more time to talks.
