Hazrat Hussain Mashreqiwal, spokesman for the police chief in Nangarhar province, said at least six civilians, including two women and two children, were killed when their vehicle was struck by a roadside bomb that wounded another two civilians.
He says two students were killed in a separate bombing that wounded a third civilian. No group has claimed responsibility for the attacks.
Taliban insurgents frequently target the army and police with roadside bombs, which have also taken a heavy toll on civilians.
