Bomb disposal experts in Germany will attempt to defuse a British bomb dropped during the second world war.
The city of Koblenz, in the west of the country, is being evacuated while the operation takes place.
Around 45,000 residents have been moved, with seven nursing homes, two hospitals and a prison being emptied.

Officials cleared an area with a radius of 2km (1.2 miles) from where the 1.8-ton bomb was found.
Trains and vehicles in the area will be stopped during the delicate operation.
The device was discovered last week along with a 275lb bomb dropped by American troops.
They emerged when the water levels in the Rhine fell after the area experienced a particularly dry spell.
