The continuing price rises for food may lead to protests and endanger the political stability worldwide, an UN official warned, after two days of widespread protests in Egypt, caused by doubling prices to basic food products in less than an year, The Guardian informs in its online edition.

Sir John Holmes, undersecretary general for humanitarian affairs and the UN's emergency relief coordinator said, during a conference in Dubai, that the price growth for food will trigger protests in vulnerable countries.

"The security implications should also not be underestimated as food riots are already being reported across the globe," Holmes said. "Current food price trends are likely to increase sharply both the incidence and depth of food insecurity."

The global average price for food increased 40% since last summer. Two weeks ago, the UN Food Program launched an emergency appeal, asking for 500 million dollars (325 million euro) during the following month, in order to maintain feeding some 73 million people worldwide.
