Suspected accomplices of those involved in the attack are being held by police, according to reports.
"It is a terror attack, there is no doubt about that," he said, in a statement, BBC reported, adding: "This attack was carried out from a vehicle driven by one person, perhaps accompanied by another, which rammed its way at high speed into this establishment which contained bottles of gas."
