• 19 December 2016 – Polish lorry driver Łukasz Urban, 37, has his vehicle hijacked in the heart of Berlin. Shortly after 8 pm local time – The hijacked truck veers into a traditional Christmas market in the shadow of the Kaiser Wilhelm Memorial Church. Eleven people are killed by the lorry, and Urban is stabbed and shot dead in the cabin. Then a 23-year-old Pakistani asylum-seeker is arrested by mistake after being chased by a pedestrian.

• 21 December 2016 – Anis Amri, a Tunisian man with connections to ISIL, whose asylum request to Germany had been rejected,[115] is announced as the new chief suspect after his documents were reportedly found in the wreckage of the hijacked lorry. He is said to have been using six different names under three different nationalities. Later in the day, a reward of up to €100,000 (£85,000) is offered by German authorities for information leading to Amri's arrest. The country's security is placed under fresh scrutiny following revelations that covert surveillance of the 24-year-old Amri had been discontinued after more than six months, due to police finding nothing to substantiate an initial tip-off.

One policeman is injured. 10 am – Italian interior minister Marco Minniti holds a morning press conference to announce, with "no doubt", that Italian police had killed the Berlin terrorism suspect.
