Rav Ovadia: All Must Go Pray Wednesday
Arutz Sheva (so far, only in Hebrew) reports that the prayer rally on Wednesday will feature representatives from all walks of Torah-based Jewish life.
Rav Ovadia Yosef said that it is obligatory for all to join in the prayer rally on Wednesday.
He also said, "I pray every day, but we need to make a mass prayer. And even if a sharp knife is placed on a person's neck, one should not give up hope from [Heavenly] mercy," quoting from Berachot 10a.
Update: The English version has it now too.
