The investigators have now arrived on the scene. They are staying at Colonel Georg Klein's base in Afghanistan, where they are questioning personnel, inspecting the premises and equipment and listening to recordings of radio communications. Their goal is to determine whether Klein can be held accountable for what happened.
Colonel Georg Klein is still in Kunduz, even though his six-month tour of duty there was scheduled to end this week. Under normal circumstances, he would have been able to go home by now, but Klein is forced to remain in Kunduz; if he were to leave Afghanistan, it would look like an admission of guilt.
He meets daily with the chief investigator, Canadian NATO Major-General C.S. Sullivan. By now Klein is probably asking himself how it could have happened, how he could have issued that fateful command on Sept. 4. Sources in Kunduz say his nerves are becoming increasingly frayed.
His command -- "Weapons release!" -- consisted of only two words. And yet it appears to have led to the killing of 100 people, including civilians, in addition to reigniting the debate over the German military mission in Afghanistan.
"At 1:51 a.m., I decided to give the order," Klein writes in a report on the incident submitted to the German Defense Ministry in Berlin. After that, two American F-15 fighter jets dropped two bombs, hitting two tanker trucks a group of Taliban militants had hijacked more than five hours earlier.
It now seems clear that the air strike was a mistake. But there are growing indications that Klein may have violated regulations in the process. Investigators are looking into whether Klein properly informed the pilots over the gravity of the situation and whether he may have skipped a level in the escalation ladder.
The air strike has changed the political situation in Germany. The left-wing Left Party -- the only major German political party that advocates an immediate withdrawal from Afghanistan -- took advantage of the incident to call for a major antiwar protest at Berlin's Brandenburg Gate. A short time later, Foreign Minister Frank-Walter Steinmeier unveiled a plan outlining how Germany could initiate a withdrawal from Afghanistan. Nevertheless, classified International Security Assistance Force (ISAF) documents suggest that the Bundeswehr will actually be drawn more deeply into the conflict, facing the prospect of more, not less, combat action.
A new al-Qaida video released on Friday included a threatening message in German directed at German voters and Chancellor Angela Merkel and her Afghanistan policy.
In the video, Bekkay Harrach, a German-Moroccan who intelligence services believe belongs to the middle level of the al-Qaida leadership, threatens attacks on German soil if the outcome of the Sept. 27 election signals a continuation of the country's Afghanistan mission. "The German government is not taking the threat from al-Qaida seriously enough," Harrach says in the video, which government officials believe is authentic. The terrorist also warns Muslims living in Germany to avoid any places that are not "essential to daily life" during the two weeks following the election. Since Friday, federal police officers armed with submachine guns have been stationed at German airports and train stations in response to the al-Qaida threat. The conflict in Afghanistan is suddenly making its presence felt in Germany.
