From the PressTV article, emphasis mine:

A Saudi journalist working for London-Based Asharq Alawsat says the Saudi monarch has been clinically dead since Wednesday. […]

It is the second time in the past months that Asharq Alawsat reports the death of King Abdullah.

In November 2012, the daily reported that Saudi king has slipped into coma and was clinically dead nearly a week after he underwent a 14-hour-long back surgery in a hospital in the Saudi capital, Riyadh.

No other news outlets appear to be reporting this.

In addition, I couldn’t find mention of it on Asharq Al Awsat’s English site, nor could I find anything on the front page of the Arabic site after running it through Google’s translator.
