Russian Foreign Minister Sergei Lavrov said on Friday, June 28, Russia is committed to arranging a peace conference on the Syria conflict but other countries and groups were complicating matters by trying to set preconditions, Reuters reported.

Lavrov, who will meet U.S. Secretary of State John Kerry next week to discuss the planned conference, also said shipments of weapons to rebels fighting Syrian President Bashar al-Assad contradicted the idea of the peace conference.
