They're not calling Palestinians Al Qaeda. The article a radical islamic group with links to Al Qaeda. That doesn't mean Islamic group with links to Palestinians. In fact this article didn't mention anything about Palestinians except that a Palestinian newsagency was the one that reported Egypt capturing 25 terrorists. The only other thing was the killing of the Gaza militant but they didn't say he was a member of Al Qaeda.
from the article: Israel issues severe travel warning: Al-Qaida may attack in Sinai
