Stressing that the situation was looking “positive compared to a few days ago”, Kevin Bell, press spokesman for Coop, told AFP that “a majority” of their stores were still closed.

On Friday, a hacking attack indirectly hit the supermarket chain, paralysing all its cash registers and forcing the company to temporarily close nearly all its shops across the country.

Bell said they had been able to reopen a few hundred stores by relying on alternative payment solutions — such as customers paying using their smartphones — and stores also allowed customers to shop online.
