Repeated explosions have prevented firefighters in Berlin from reaching a blaze in a forest to the south-west of the city that started at a police munitions site used to store second world war bombs.

The fire broke out in the early hours of Thursday morning after unexploded ordinance was accidentally detonated, according to the Berlin police.
