Five years after the Islamist terrorist attack on a Berlin Christmas market, a first aider died.

The 49-year-old died on October 5th and is now buried at his last place of residence in Troisdorf near Bonn, his husband told the German press agency on Monday evening.

The RBB had previously reported.

This means that 13 people died as a result of the terrorist attack.

Immediately after the attack on December 19, 2016, the man rushed to the aid of visitors to the Christmas market at the Memorial Church.

He was allegedly hit by a beam and seriously injured in the head.

Since then, he has had to be looked after around the clock.

His husband died of an infectious disease as a result of the long-term illness, said the widower.

Astrid Passin, who speaks on behalf of many victims and bereaved families, has now sent a letter to the Berlin Senate Chancellery.

In it, she asks that the name of the now deceased 49-year-old also be listed on the steps of the memorial at the Memorial Church in Berlin.

In the letter to the MPs and the Senate Chancellery, she hopes, according to the RBB report, "unbureaucratic implementation by the 5th anniversary on December 19".

The Tunisian Anis Amri shot a truck driver in Berlin on December 19, 2016.

With his vehicle he raced through the Christmas market at Breitscheidplatz, where eleven more people died.

The authorities had already noticed the rejected asylum seeker as an Islamist threat.

After the attack, he fled to Italy, where he was shot by the police.

Numerous mistakes by the security authorities

After four years of examination, the investigative committee of the Berlin House of Representatives came to the conclusion that numerous errors in various security authorities in Berlin and in the federal government made the attack possible.

The main decisive factor was the misjudgment of the rejected asylum seeker Amri in the summer of 2016.

An investigative committee of the Bundestag had, among other things, analyzed the role of the Federal Criminal Police Office (BKA) and also found striking misjudgments of the assassin there.
