(CNN) There have been eight lethal terrorist attacks in Europe since 2014, five of them in France alone, carried out by ISIS or by "lone wolves" inspired by the terror group or by al Qaeda. What do these attacks have in common? The terrorists are almost invariably criminals who have either served time in the French or Belgian prison systems, or they have been convicted for lesser offenses but have avoided jail time. Mohamed Lahouaiej-Bouhlel, who killed at least 84 people Thursday in Nice, France, had a long record of petty crimes. Bouhlel assaulted a motorist last year for which he received a six-month suspended sentence.Peter Bergen: Many of those behind terror attacks in Europe shared criminal backgroundConditions in French prisons incubated the radicalization of many terrorists, he says

Washington (CNN) -- An alleged Somali pirate leader has been indicted for the takeover of the yacht Quest and the kidnapping of four Americans who subsequently were killed during the incident. Mohammad Saaili Shibin, 50, appeared at a detention hearing in federal court in Norfolk, Virginia, on Wednesday afternoon after the indictment against him was unsealed. He will remain in federal custody. "Today marks the first time that the U.S. government has captured and charged an alleged pirate in a leadership role -- a hostage negotiator who operated in Somalia," said U.S. Attorney Neil MacBride in a written statement. MacBride went on to say the arrest and charges against Shibin should "send a strong message to all pirates that they are not beyond the reach of the FBI, whether they board the ships or remain on-shore in Somalia."Four Americans died during the hijacking of a yacht in FebruaryThe purported leader of alleged pirates was arrested in Somalia on April 4A prosecutor says the indictment marks the first U.S. prosecution of a pirate leader

With his blond mohawk, nose ring and painted toenails, Charles Johnson is not afraid to stand out. A year ago he was doing anything but. Hidden away on the Cleveland Browns practice squad after recovering from an ACL injury, the Minnesota Vikings took a punt on the wide receiver. He began slowly with just three catches by week eight, but Johnson blossomed into Teddy Bridgewater’s favourite target down the stretch, catching 25 balls in the final seven games as the Vikings’ offense whirred into action. And now he’s ready for a breakout season. With Minnesota widely tipped as a dark horse for the play-offs, the burgeoning relationship between Johnson and second-year quarterback Bridgewater will be key. The pair made their first appearances for the franchise during a heavy week three defeat in New Orleans but began to click after Johnson ousted Cordarrelle Patterson as the Vikings’ top split end receiver.Johnson joined the Vikings last season from the Browns practice squadDown the stretch he impressed as Bridgewater's favourite targetWith Peterson's return, a fully fit Kyle Rudolph and Mike Wallace, the Vikings have a potent-looking offenseJohnson points to the strength of the roster and the presence of head coach Zimmer as reasons for optimism in Minnesota

_ is yet to play with the arguably the greatest running back in the game, but he has got to know Peterson at close quarters.
