Afghan roadside bomb kills 18 wedding guests

A massive roadside bomb has killed at least 18 people on their way to a wedding in northern Afghanistan.

At least 15 others have been wounded in what a BBC correspondent called one of the worst such attacks in the country for some time.

A minibus was carrying men, women and children to the wedding in the Dawlatabad district of Balkh province when it was struck by the bomb.
