WASHINGTON (AP) — The head of the International Monetary Fund says that six years after the financial crisis, the world is still mired in a disappointing economic recovery and will only be able to regain momentum through improved government policies.

IMF Managing Director Christine Lagarde said Thursday that the world has experienced a sub-par recovery that is “brittle, uneven and beset by risks.” Those risks include potential escalation of the strife in the Middle East and Ukraine, as well as the Ebola outbreak in Africa.
