An aerial view of flood waters is seen over Pakistan's Rajanpur district in Punjab province on August 14, 2010. The floods, triggered by torrential monsoon downpours just over two weeks ago, engulfed Pakistan's Indus river basin, killing up to 1,600 people. United Nations aid agencies have provided assistance to hundreds of thousands of victims of Pakistan's worst floods in decades but relief operations have yet to reach an estimated six million people.
