A third Polish supermarket has been hit by an explosion, this time in Beverwijk, west of Amsterdam.

The back wall of the supermarket in the Beverhof shopping centre was badly damaged by the blast, which happened at around 5.15 on Wednesday morning. No-one was injured and unlike in the previous two blasts, no-one lived near to the store and had to be evacuated.

The Beverwijk shop has the same owner as the store in Aalsmeer which was targeted on Tuesday. Owner Mohamad Mahmoed told the AD the new attack is ‘unbelievable’.

The second Tuesday explosion took place in Heeswijk-Dinther, south of Den Bosch, an hour after the Aalsmeer attack.

The supermarkets were initially reported to be part of the Polish discount chain Biedronka but a spokesman for the company has told DutchNews.nl that this is not the case and that the group does not operate outside Poland.

Police are now investing the link between the three attacks.
