BERLIN - The German military's top official was removed Thursday for failing to properly pass on information to political leaders about a September airstrike in Afghanistan in which civilians were killed, the new defence minister said.

Karl-Theodor zu Guttenberg told parliament that the military's inspector general, the equivalent to chief of staff, Gen. Wolfgang Schneiderhan, had asked to be relieved of his duties after Germany's top-selling Bild newspaper published what it said were still captures from confidential videos of the incident.

Peter Wichert, a deputy defence minister who was in office at the time of the airstrike, also stepped down.

Bild reported that the videos showed it was likely civilians were killed, and that the videos were in German hands at a time when then-Defence Minister Franz Josef Jung was insisting that there was no evidence of civilian victims.

Guttenberg said, however, that Jung had not seen the videos, and that he himself had only been shown them on Wednesday. Jung is now Germany's labour minister.

A German colonel called in the NATO airstrike against two tanker trucks that had been seized by Taliban insurgents near Kunduz, fearing they could be used to attack troops.

Thirty civilians and 69 armed Taliban died in the strike, according to a probe by an Afghan presidential commission.

Earlier this month, Guttenberg said a classified NATO report concluded there were "procedural errors" in the Sept. 4 airstrike, but defended the decision by the colonel to request it as "appropriate in military terms."

At the time, Guttenberg said he assumed there were civilian victims, based on his assessment of the NATO report.

"I regret ... every civilian victim deeply," he said.

The report was prepared by the NATO-led International Security Assistance Force.

The top U.S. and NATO commander in Afghanistan, Gen. Stanley McChrystal, appointed a Canadian major general to lead the investigation along with officers from the U.S. Air Force and German military.

Germany has more than 4,000 troops serving in northern Afghanistan and 36 have been killed so far in the mission.

Guttenberg has taken a plain-talking approach to Germany's unpopular mission in Afghanistan since taking over the Defence Ministry after September elections.

He has acknowledged that the situation in parts of Afghanistan is "similar to war" -- a description Jung always avoided.
