Europe has been left reeling after a night of terror has left several people dead. Fatal attacks by apparent terrorists occurred Sunday and Monday in Germany, Turkey and Zurich.

At least 12 people were killed and dozens were injured, several critically, when the truck crashed into a busy Christmas market in Berlin, Germany.

Russia’s ambassador to Turkey Andrei Karlov was shot dead at a photo exhibition in Ankara, Turkey.

A gunman injured several people at a mosque in Switzerland’s largest city, Zurich.

Truck ploughs through crowd at Berlin Christmas market

A truck slammed into a crowded Christmas market in central Berlin on Monday night, killing at least 12 people and wounding 48.

The incident took place at the Christmas market at the Kaiser Wilhelm Memorial Church near the Zoologische Garten train station in the western part of the city. The popular Christmas market was filled with a mix of tourists and locals when the large Scania truck hurtled into it.

The Berlin truck attack evoked scenes of Nice, France, where a truck drove into a crowd in July, killing over 80 people.

Russian Ambassador to Turkey assassinated in Ankara

Russia’s ambassador to Turkey was assassinated at an Ankara art exhibit on Monday evening by a lone Turkish gunman shouting “God is great!” and “don’t forget Aleppo, don’t forget Syria!” in what the leaders of Turkey and Russia called a provocative terrorist attack.

President Vladimir V. Putin of Russia said on Russian television that Mr. Karlov had been “despicably killed” to sabotage ties with Turkey. Mr. Putin spoke with the Turkish president, Recep Tayyip Erdogan, by phone, and the two leaders agreed to cooperate in investigating the killing, and in combating terrorism broadly.

At least 3 injured after gunman opens fire in Zurich mosque

A man stormed into a Zurich mosque on Monday evening and opened fire on people praying, injuring three, near the main train station in Switzerland’s financial capital.

Two of the three men — aged 30, 35 and 56 — were seriously injured in the attack shortly after 5:30 p.m. local time (1630 GMT) near the main train station in Switzerland’s financial capital, Zurich police said.

The unidentified suspect, a man around 30 years old who according to witnesses was wearing dark clothing and a dark wool cap, fled the mosque, police said.

Two thirds of Switzerland’s 8.3 million residents identify as Christian but the nation has been wrestling with the role of Islam as its Muslim population has risen to 5 percent, swelled by the arrival of immigrants from the former Yugoslavia.
