Paris - A terror attack in London on June 3 claimed by the Islamic State group left eight people dead after three men in a van drove at pedestrians on London Bridge and then stabbed nearby Saturday night revellers.
It was the latest in a deadly series of attacks linked to radical Islamists against European targets in the last two years.
France on the frontline
France has been hit the hardest, with 238 deaths since early 2015.
The first attack comes on January 7, 2015 when two brothers who claim allegiance to Al-Qaeda gun down 12 people in an attack against the satirical weekly Charlie Hebdo in Paris.
The next day, a man linked to the Islamic State group (IS) shoots dead a policewoman in a Paris suburb.
He takes hostages in a Jewish supermarket near Paris the following day, killing four people.
All three gunmen are killed by police.

On November 13, 2015 France suffers its worst ever terror attack, when suicide bombers strike several targets, killing 130 people and wounding 350.
