Firefighters were Wednesday battling a blaze at an oil refinery in southern Britain following reports of an explosion, the BBC said, according to dpa. Fire engines and ambulances rushed to the scene of the fire, in Coryton, in the southern county of Essex, but there were no immediate reports of injuries. Essex Fire Services said they were checking reports of an explosion. In December, 2005, an explosion and fire at the Buncefield oil storage depot near Hemel Hempstead, north of London, injured more than 40 people and prompted large-scale evacuations of nearby homes. dpa at ds
