The Taliban beheaded 17 partygoers, including two women dancers, in Afghanistan's volatile Helmand province as punishment, recalling the darkest days of rule by the ultra-conservative Islamist insurgents before their ouster in 2001.

The bodies were found on Monday in a house near the Musa Qala district where a party was held on Sunday night with music and mixed-sex dancing, said district governor Nimatullah. Men and women do not usually mingle in Afghanistan unless they are related, and parties involving both genders are rare and kept secret.

The killings, about 75 km north of the provincial capital Lashkar Gah, came at the beginning of a violent 24 hours for NATO and Afghan authorities in which 10 Afghan soldiers were killed in a mass insurgent attack, also in Helmand, while two US soldiers were slain by a rogue Afghan soldier.
