The Russian President Vladimir Putin has declared the attack in St Petersburg on Wednesday was a terrorist attack.
Putin was speaking at an awards ceremony in the Kremlin for Russian military servicemen and women who served in Syria.
He said to the audience: “You know that yesterday in St Petersburg a terrorist act was carried out.
“And that recently the Federal Security Service prevented another attempted terrorist act.”
There were 13 people injured when an improvised explosive deice went off in a busy supermarket.
Five of the eight victims are in hospital with serious injuries.
The explosion was caused by a homemade explosive device filled with lethal fragments.
The attack took place in Russia’s second-largest city and the site of a deadly train bombing this year.
According to Russia’s investigative committee, a device containing 200 grams of explosives went off in a storage area for customers’ bags.
Putin has been in contact this month with President Trump to thank him after the CIA helped Russia to thwart a series of bombings in St Petersburg.
