The Memorial to the Murdered Jews of Europe, one of the German capital's most sacred sites, commemorates the six million Jews murdered by Adolf Hitler's Nazis during World War Two.
The suspect in a stabbing at Berlin’s Holocaust Memorial two days before Germany’s election was a Syrian refugee who apparently wanted to kill Jews, according to prosecutors.
Video of city centre, near the Brandenburg Gate, showed emergency vehicles and heavily armoured police lined along one side of the 1.9 hectare (4.7 acres) memorial site, which had been sealed off as investigators combed the scene.
At the time of his arrest, he was carrying a backpack containing a prayer mat, a Quran, a sheet with verses from the Quran as well as Friday's date, and the knife allegedly used in the attack.
An eyewitness told local broadcaster RBB24 that two men had appeared to approach each other before the victim was suddenly stabbed at around 6pm local time (5pm UK time).
