German far-right rally hears calls for violence against foreigners

People take part in a march in Koethen, eastern Germany, on Sunday.

(CNN)Around 2,500 people gathered in the eastern German city of Koethen Sunday for a right-wing demonstration after two Afghan men were arrested for assaulting a 22-year-old man who later died, according to police.

The "funeral march," which drew far-right groups from Goettingen, 110 miles west of Koethen, and from Greiz, a two-hour drive to the south, bore strong echoes of the demonstrations in the city of Chemnitz two weeks ago, which were triggered by the death of German-Cuban man Daniel Hillig and the subsequent arrest of an Iraqi and a Syrian man and which saw hundreds calling for foreigners to leave Germany.
Fearing a similar escalation of violence, Koethen Mayor Bernd Hauschild warned against attending the march and advised local citizens to mourn the man's death at a commemorative event earlier in the afternoon.
    Explaining his advice, Hauschild wrote in a Facebook post Sunday afternoon that he had "been informed that violent groups from outside Koethen will travel in large numbers" to attend.
    State Interior Minister Holger Stahlknecht said Monday that between 400 and 500 of the 2,500 demonstrators were members of the "right-wing scene."
    Local police said Sunday that the 18- and 22-year-old suspects, both from Afghanistan, were being held on suspicion of causing bodily harm with fatal consequences.
    But speaking Monday, Sachsen-Anhalt state Justice Minister Anne-Marie Keding confirmed media reports that the victim suffered from heart disease and died of a heart attack, adding that "fatal injuries could not be detected."

    David Koeckert, a leading figure in far-right group Thuegida and former member of the NPD, a right-wing extremist party, was one of those who traveled to Koethen following multiple calls to action across social media.
    Hundreds listened to Koeckert's speech at the event, many clapping and cheering as he described immigration to Germany as an "invasion" and warned of the "slaughter of the German people."
    "This is war and can be described as such. A race war against the German people," Koeckert said. "Do you want to remain bleating sheep or do you want to become wolves and shred them?"
