By Maria Tsvetkova and Pavel Polityuk MOSCOW/KIEV (Reuters) - Ukrainian military pilot Nadiya Savchenko arrived home to scenes of jubilation on Wednesday after her release by Russia in a prisoner swap and she promptly offered to fight again for Kiev in its conflict with pro-Russian separatists. Savchenko's handover, in return for two Russian prisoners - had been demanded by the West and was cast as a humanitarian gesture by Russian President Vladimir Putin a few weeks before the European Union decides whether to extend sanctions against Russia imposed over its support of the rebels. Savchenko, 35, barefoot - it was unclear why - and wearing a T-shirt depicting the Ukrainian coat of arms, emerged from the terminal at Kiev's Boryspil airport to cries of "hero" from a crowd of supporters, among them her sister and mother.
By Valerie Volcovici WILLISTON, North Dakota (Reuters) - Two energy advisers to Donald Trump want him to call out members of the Organization of the Petroleum Exporting Countries for driving down world oil prices when he delivers a major energy policy speech this week. The advisers, who said they had been asked by Trump's 2016 presidential campaign to contribute ideas for the speech, told Reuters they had also suggested he mention cuts to regulations and a streamlining of the federal tax code to make U.S. energy companies more competitive. The advisers, U.S. Congressman Kevin Cramer of North Dakota and another who asked not to be identified, said they had urged Trump to criticize the OPEC cartel for contributing to a crash in world oil prices by producing full throttle, a factor that has helped push many U.S. oil companies into bankruptcy.
