One person was missing after a river of mud unleashed by heavy rains flooded a tiny village on Italy's Amalfi Coast.

Video footage showed the mud running through a small alley in the village of Atrani, tipping cars over and almost entirely covering some of them.

Officials said a small river close to the village had broken its banks, fed by heavy rains.

Brunella Cimadomo of the Civil Protection Department said a 25-year-old woman was missing after the coffee bar where she worked was hit by the mudslide. She said the rain had let up today but more was expected in coming days.
