In November 2015, a series of coordinated attacks occurred in Paris. Three suicide bombers struck outside the Stade de France in Saint-Denis, the northern suburb of Paris during a football match. This was followed by several mass shootings, and a massive hostage situation in the Bataclan theater. The attackers killed 130 people, including 89 at the theater, and left 368 people injured.
Half a year later also in France, at least 84 people were killed and 303 were injured when a truck plowed into a crowd during Bastille Day celebrations in Nice. ISIL claimed responsibility for this attack.
In March 2016, 32 people were killed and hundreds wounded in suicide bomb attacks in Brussels, Belgium. Two suicide bombers blew themselves up at Brussels Airport while another ignited in a train at a busy metro station, killing 16 more passengers.
Later in the same year in Berlin, 12 people were killed and dozens injured after a truck attack on a popular street Christmas market. A failed Tunisian asylum seeker named Anis Amri was suspected of carrying out the attack. He was shot dead by Italian police four days after the attack.
On the other side of the English Channel, in March 2017, Khalid Masood mowed down pedestrians on Westminster Bridge, London, killing four people and injuring many others. He was shot dead by armed police later.
Most recently in Sweden, a hijacked beer truck plowed into pedestrians at a central Stockholm department store in April 2017, leaving 4 people dead and 15 injured. All the attacks in Belgium, Germany, Britain and Sweden were claimed by terrorist group ISIL.
Europe has bolstered security in a bid to prevent such attacks from occurring. Just days before the first round of France's presidential election, on April 18th, 2017, police thwarted an imminent "terror attack" and arrested two men in the southern port city of Marseille, finding guns, explosives and an ISIL flag.
