Tom Perry slipping in assertions which have no basis in reality

An assertion:

is commonly used in advertising and modern propaganda. An assertion is an enthusiastic or energetic statement presented as a fact, although it is not necessarily true. They often imply that the statement requires no explanation or back up, but that it should merely be accepted without question.

In a story on the arrest of Mohammed Khatib for his role in organizing illegal and violent protests in Israel, Reuters correspondent Tom Perry writes:

The Fatah party of Palestinian President Mahmoud Abbas, who opposes violence against Israel, wants more "popular resistance" against Israeli occupation and West Bank settlement policies.

This is not the first time Perry has issued the completely unsubstantiated assertion that Abbas (and Fatah) opposes violence.  Where is Perry's evidence for this notion?  He has none to offer.  In fact, Abbas has consistently voiced support (in Arabic) for Palestinian violence aimed at Israel:

We have a legitimate right to direct our guns against Israeli occupation.

Fatah dictates the same in both its Constitution and decrees:

Another resolution stated that Fatah will not give up the armed struggle until all the descendants of those claiming to be of Palestinian Arab origin can live inside Israel.

Perry is keen to disseminate unsupported assertions but conspicuously silent on matters of record.
