Non Hezbollah groups 

Hello. I was wondering, is worldnetdaily considered a reliable source according to Wikipedia; Since it is the source used when mentioning the Iranian deaths?
Also, the source cited when mentioning the PFLP is the Jerusalem Post and it doesn't mention that the PFLP were engaged in combat against the IDF. It says that the IDF bombed their bases. So should the PFLP be included in the list of belligrents?
