BERLIN (AFP) - Germany has been hit by a spate of attacks, the deadliest of which struck a Christmas market in Berlin in December 2016, leaving 12 dead.
On Friday (July 28) a man wielding a knife stormed into a supermarket in the German city of Hamburg, killing one person and wounding four others before being detained by police.
His motive was not immediately clear, but mayor Olaf Scholz spoke of "hate" behind his actions, while media reported that authorities were investigating the attacker's Islamist connections.
