Iran Denies Militia Backing in Iraq

Tension in the Middle East is increasing by the day.  The latest confrontation that has occured in the Middle East is between Iran and Iraq(not surprising).  Iran was accused of supplying Iraqi's with missles and other weapons and training Iraqi soldiers.  However, Iran denies any involvement with the Iraqi militia.  Iran military officials claim that Iraq has all the weapons and missles they need and there would be no point to smuggle illegal weapons across the border.  Another Iran military official also stated that this rumor may have been started to create tension between the two countries.  However, tension has already been created between the two way before this issue even arose.  

When will the problems in the Middle East end???
