The interior ministry has not commented on the plans – which were revealed by the Frankfurter Allgemeine Sonntagszeitung newspaper – but says a civil defence strategy is due to be discussed on Wednesday.

The article quoted the government document as saying that everyone will need a 10-day supply of food and five-days worth of water.

Germany’s currently on hight alert after two Islamist attacks and a shooting rampage.

The newspaper said a parliamentary committee had originally commissioned the civil defence strategy in 2012.

Social media response

The proposed precautions have got a comical response on social media – with some likening the stockpiling of supplies to that of hamsters filling their cheeks. (Euronews)
