Severe drought in Russia has sent world food prices 5 percent higher in recent months, according to a new report by the United Nations, and though they remain well below the record levels reached during the 2007-08 world food crisis, the higher prices have already fueled deadly riots in Mozambique. (..) Elsewhere, a separate report Tuesday by the U.N. World Food Program (WFP) warned that Pakistan's woes were only beginning. "There is a triple threat unfolding as this crisis widens and deepens," WFP's executive director, Josette Sheeran, said in a prepared statement after touring the flood-ravaged nation. "People have lost seeds, crops and their incomes, leaving them vulnerable to hunger, homelessness and desperation -- the situation is extremely critical. We urgently need continued and strengthened commitment to the people of Pakistan in this time of crisis."
