The German government indicated Wednesday that it was willing to pay further compensation to the families of 11 Israeli athletes who were killed at the 1972 Summer Olympics in Munich by members of a Palestinian group.

Relatives of the athletes have long criticized how German authorities handled the attack and its aftermath. Demands for further compensation have threatened to overshadow a planned memorial event for the 50th anniversary of the massacre.

Germany’s Interior Ministry said it was currently holding talks with the relatives and that the “serious consequences for the surviving dependents of the victims in immaterial and material terms” should be reassessed.

“An offer of further recognition payments to the surviving relatives of the victims of the attack” was planned, the ministry told German news agency dpa adding that “the memorial ceremony of the 50th anniversary should be the occasion for a clear political classification of the events of 1972.”

It was not clear how much money would be offered to the families of the victims.

Members of the Palestinian group Black September broke into the Olympics Village and took athletes from Israel’s national team hostage on Sept. 5, 1972, with the goal of forcing the release of prisoners held by Israel and two left-wing extremists in West German jails.

Eleven Israelis and a West German police officer died during the attack, including during a botched rescue attempt.

Immediately after the attack, Germany made payments to the relatives of the victims amounting to about 4.19 million marks (about 2 million euros or $2.09 million), according to the Interior Ministry. In 2002, the surviving relatives received another 3 million euros, dpa reported.

A claim for compensation payments amounting to around 40 million marks cited massive errors in the police operation, but it was dismissed because of the statute of limitations.

In Israel, Ilana Romano, the widow of Yossef Romano, a weightlifter who was one of the first Israelis killed, told public broadcaster Kan on Tuesday that Germany’s current reparations offer was “degrading” and the victims’ survivors rejected it.

“The offer is degrading, and we are standing by our stance that we are boycotting the (anniversary) ceremony,” she said, adding that Germany “threw us to the dogs. They mistreated us for 50 years.”

“They decided to take responsibility — very nice after 50 years,” Romano said, calling for proper compensation for the families “not pennies.”

Demands to release previously unpublished files on the attack were met last month, when officials in Bavaria said they would release any files under wraps in the southern German state.
