The German prosecution is considering reopening the investigation into the terror attack on a Jewish retirement home in Munich in 1970, in which seven seniors were burned to death. The German magazine Focus reported that it uncovered "vital information" on the perpetrators, who were never captured.

The report prompted the police to start some investigative procedures, despite the fact that some of the information reported was found to be incorrect. According to the report, the new information has to do with the only physical evidence left on the scene – a fuel tank used to set the building ablaze. Due to the advances made in DNA technology, the culprits' identities may be discovered.

In addition, the magazine claimed it had "substantial evidence" that the attack was carried out by activists in the German radical left and not by right-wing extremists or Palestinians as originally thought.

"They were extremely radical. They spoke only of the Israeli enemy and wanted to form a real front," ex-left wing radical activist Aloise Aschenbrenner told the magazine.

The attack on the Jewish retirement home took place in February 13, 1970. To this day, it is still unknown who was responsible for the attack, despite the fact that the initial investigation was led by a team of one hundred detectives and that a 100,000 Deutsche Mark award was offered to anyone who was willing to give out information that would lead to an arrest.

The report states that one of the names potentially linked to the attack is Dieter Kunzelmann, who is known as a "Jew-hating anarchist." In the fall of 1969, Kunzelmann took part in a Palestinian terrorist training camp in Jordan. In November of that year he returned to Berlin, there he was involved in a failed terrorist attack on Jewish community center.

Even though not all of the victims in the attack were Jewish, six of them were brought for burial in Israel. One of them was David Yakobovich, a Polish Holocaust survivor. Yakobovich was buried in Kibbutz Yad-Mordechai. The seventh victim was buried in Germany.

Another piece of evidence supporting the theory that the attack was carried out by radical activists is a German federal police document composed in 1976, documenting a phone call between two female senior officials in the Bader-Meinhof terrorist organization. According to the report, the phone call reveals that the officials knew who carried out the attack and that the two were pleased that neo-Nazis were incriminated for it.

In addition to the Focus report, a new documentary to be aired next week on German television claims that the radical left was responsible for some terrorist acts and attempts made on Israeli and Jewish targets across Germany in the 1970s.

Except for the attack on the retirement home in Munich, the documentary also mentions the bombing of Swissair flight no. 330, departing from Zurich to Tel Aviv in 1970. 47 people were killed in the attack, 25 of which were Jewish or Israeli. Another is the attack on passengers of the Israeli airline El-Al in Munich's airport, carried out only three days later, where 32-year-old Arie Katzenstein was murdered.
