The German defence minister, Peter Struck, blames the al Qaeda terrorist organisation for the attack on German soldiers in Kabul on Saturday. He says the suicide bomber who killed four German soldiers and wounded 29 others had contacts to the group. Struck adds that the attack was financially and logistically supported by the militia leader, Gulbuddin Hekmatyar, and former Taleban. Struck says these three groups are trying to drive the international peacekeeping force out of Afghanistan.
