Ten people were killed and 44 injured in Germany on Friday when a freak sandstorm caused a motorway pile-up involving at least 80 vehicles. Police said 17 cars and three lorries went up in flames in the mass collision at Kavelstorf, near the Baltic Sea coast.They said the pile-up was likely caused when winds swept up loose topsoil from a recently plowed field, blocking the drivers' view. It took emergency workers until late in the evening to clear the stretch of motorway.<br />RT on Facebook: http://www.facebook.com/RTnews<br />RT on Twitter: http://twitter.com/RT_com
