Responsibility
There was no claim of responsibility for the blast but there were about 120 suicide attacks in Afghanistan in 2007, most of them blamed on the Taliban movement. A spokesperson for the Interior Ministry blamed the attack on "the enemy of Afghanistan, the enemy of the people of Afghanistan" referring to the militant group. Following the bombing, a Taliban official dismissed any responsibility of the group for the incident. The attacks have worsened since the fall of the Taliban in 2001.
One person was arrested and questioned the following day. According to the BBC, several claims told that it was not a suicide attack and that it was possible a roadside bomb or a rocket attack.
On the same day as the Baghlan bombings, Taliban rockets were fired at an Afghan base near Kandahar during a visit by Canadian Defense Minister Peter MacKay, injuring several soldiers. That incident was likely unrelated to the Baghlan bombing.
