The claim that more than 300 projectiles fired by Hezbollah crossed into Israel over Yom Kippur weekend, based on what I've found, seems to be leading to false or exaggerated/misleading. According to CNN, Barrons and Radio Free Europe, however, the CNN and Barron articles don't give very much information and don't list any sources for their information. The RFE use quotes from unnamed military personnel. They also write that Hezbollah claimed these strikes but, PBS has reported that Hezbollah has only claimed two missiles hitting Israel over Yom Kippur, and only one of those detonated. This story is not reported by any other major news agencies. To me this says the information is mostly false found in the CNN article is mostly false and exaggerated.
