Repeated explosions have prevented firefighters in Berlin from putting out a blaze in a forest to the south-west of the city that started at a police munitions site. 
More than 100 firefighters were battling the fire in the German capital's well-to-do Grunewald district in the west of the city, reported Deutsche Presse Agentur. Homes were not directly threatened by the flames, but the fire department warned that the blaze could spread further due to the forest's dryness and the exceptional heat expected on Thursday, when temperatures may reach 38C
