Russian Foreign Minister Sergey Lavrov says any new international negotiations on easing Ukrainian tensions should include pro-Russian rebels in the east and south of Ukraine.
Lavrov says he is not against a follow-up meeting to the 17 April round in Geneva, where he was joined by Ukraine Foreign Minister Andriy Deshchytsia, US Secretary of State John Kerry and EU representative Catherine Ashton.
But he told reporters Wednesday that such a meeting would not "have any added value" unless representatives of the rebels are also invited.
The previous Geneva meeting called for the dissolution of all illegal military formations in Ukraine. It also said those occupying buildings must leave them and be disarmed and suggested an amnesty for all anti-government protesters.
