In continuation of what Rav Kanievsky Shlita
said about the coming redemption, that by next year Moshiach will be here and we will no longer be fasting 9 Av, HaRav Dov Kook Shlita said in Teveria in his weekly shiur to his students, "Do not leave the borders of Israel between 9 Av till Rosh HaShana because difficult things will occur in the world during this time."
Harav Binyahu Shmueli Shlita said 2 weeks ago that within 80 days the redemption will begin.
Harav Eliezer Berland Shlita told his Chassidim not to purchase flight tickets to Uman this year till further notice. He also said some hair-raising warnings about hostilities that could erupt in the world before Rosh Hashana.
