Did Yazeed Really killed Hazrat Hussain (R.A) ?

Re: Did Yazeed Really killed Hazrat Hussain (R.A) ?

There is another theory in this regard that People of Koofa killed Hazrat Hussain. It is also stated in some history books that Yazid Never ordered to kill Hazrat Hussain however he ordered the governor of Koofa to overcome the situation over there.
