The eruption of the Icelandic volcano Eyjafjallajokull has brought disruption to the skies over Europe.The maps above show how flights have been restricted to flying around the ash cloud, shown in red. Where the shading is darkest, it indicates the cloud is extending higher into the atmosphere. The flight ban was partially lifted on Tuesday - five days after the eruption. EU transport ministers agreed to allow limited flights within Europe after flight tests showed the density of the volcanic ash in the air was diminishing.
