Taliban insurgents beheaded 17 Afghan civilians while celebrating in Afghanistan, over the weekend.
The attack happened Sunday in the Taliban-controlled Helmand Province.
Officials said the people had gathered for a celebration where they were playing music and dancing.
Taliban insurgents wanted to stop the music. They opened fire and then chopped off the head of all the victims.
Meanwhile, an American Taliban convert is seeking the right to hold group prayer in an Indiana prison.
John Walker Lindh, who converted to Islam, filed a lawsuit against the federal government. He claimed the federal government is trampling his religious rights.
Lindh had been charged with conspiring to kill Americans and support terrorists, but those charges were dropped in a plea agreement.
He is serving a 20-year sentence for supplying services to the now-defunct Taliban government of Afghanistan and carrying explosives for them. He is eligible for release in 2019.
The lawsuit was originally filed in 2009 by two Muslim inmates in the unit. Lindh joined the lawsuit in 2010, and the case has drawn far more attention since then.
The other plaintiffs have dropped out as they were released from prison or transferred to other units.
The government said prayer in groups would pose a security risk. Lindh will testify in court today.
