Recent weeks have shocked the world with news of horrific attacks in the USA, France, Tunisia, Belgium and now, Germany, as a young Afghan refugee armed with an axe and knife is said to have attacked and injured at least four people on a train.
The incident occurred in southern Germany.
Reports say police responded swiftly to the terror attack and shot the blood-thirsty passenger dead, to save lives.
A total number of three persons sustained serious injuries while one suffered minor cuts.
Previous reports put the number of victims at 20 but it was later revealed that out of the 20, about 14 persons were treated for shock.
Police said the motive for the Wurzburg attack is not yet clear but investigations are underway.
Bavarian Interior Minister Joachim Herrmann said the attacker was a 17-year-old Afghan refugee who had been living in the nearby town of Ochsenfurt.
He told public broadcaster ARD that the teenager appeared to have traveled to Germany as an unaccompanied minor.
Mr Herrmann said authorities were looking into reports that the attacker had yelled out “an exclamation”. Some witnesses quoted by German media said they had heard him shout “Allahu akbar” (“God Is Great”) during the attack.
The incident happened at about 21:15 (19:15 GMT) on the train which runs between Treuchlingen and Wurzburg.
“Shortly after arriving at Wurzburg, a man attacked passengers with an axe and a knife,” a police spokesman said.
According to BBC, police confirmed that said attacker had fled the train after attacking passengers, but was chased by officers who shot him dead.
While the police try to unravel the mystery behind this attack, BBC’s Damien McGuinness in Berlin says there is nervousness in Germany about attacks by Islamist extremists following the attacks across the border in France.
Recently in May, a man of same religious belief was reported to have shouted “Allahu akbar” before killing one person and stabbing another three in a knife attack at a railway station near Munich.
The assailant was later sent to the hospital for psychiatric tests but no link to any Islamic extremists was established.
