A powerful blast shocked Kunduz city, the capital of Kunduz province, in north Afghanistan on Sunday, police said.
"A roadside bomb apparently targeted a convoy of NATO-led troops in Kunduz city this morning but fortunately caused no loss of life," deputy to provincial police chief Abdul Rahman Haqtash told Xinhua.
The blast occurred in Ludin area just minutes after passing a military convoy of NATO-led troops from there, he added.
He put the attack on the enemies of peace a term used against Taliban militants but the outfit has yet to make comment.
Kunduz has been the scene of increasing militancy over the past eight months.
According to Mohammad Omar, the governor of Kunduz province, to sweep out militants from their hideouts in Kunduz province needs at least five months.
