The fragility of world security is unmatched since World War Two, requiring willingness to compromise to avoid a new global conflict, Russia's RIA agency cited Sergei Naryshkin, head of Russia's SVR intelligence service, as saying on Tuesday.

"The world is now experiencing the most fragile moment for international security since World War Two, namely a period of qualitative transformation of the global order," RIA cited Naryshkin as saying.
