MOSCOW - Syria's parliamentary elections on Wednesday aim to avoid a legal vacuum before early elections are held under a new constitution, Russian Foreign Minister Sergei Lavrov said on Wednesday. 'The Syrian sides will have to agree on a new constitution, on how they see the structures needed to ensure a steady transition to a new system,' Lavrov told a news briefing. 'There is an understanding already that a new constitution should emerge as a result of this political process, on the basis of which new, early elections are to be held.'
