German police arrested a suspect in the stabbing on Friday evening at Berlin's Holocaust memorial that seriously injured a man two days before a watershed national election.

The suspect, a Syrian refugee, told the police that a plan had come into his mind to kill Jews. The attack raises tensions just before an election in which immigration is a big issue.

Authorities in Berlin have detained a teenage Syrian refugee after a man was stabbed near the city’s Holocaust Memorial late Friday – as divisive rhetoric swells over Germany’s immigration policy, ahead of a consequential national election.
