A roadside bomb in western Afghanistan on Friday killed 17 civilians who were attending a wedding party when their minibus triggered the mine, officials said, DPA reported.
At least 14 others were injured in the incident. It was not clear whether they were going to the wedding or returning from one.
"The insurgents have again killed innocent Afghans, including women and children," Brigadier General John Madower, a spokesperson for the NATO-led international forces said in a statement.
The coalition blamed the Taliban insurgents for more than 2,800 civilian deaths and injuries this year.
The majority of these casualties are caused by Taliban improvised explosive devices (IED)s, the statement said.
In eastern Afghanistan, two NATO soldiers were killed in an "improvised explosive attack," another statement said.
