AFGHANISTAN, October 26 - Protest activity will likely increase—possibly significantly—on October 26 to commemorate the 40th day since the regime killed Mahsa Amini. Protest organizations such as the neighborhood youth groups have continued to call for countrywide demonstrations on October 26. Many protest organizations continue to use revolutionary rhetoric in describing the planned demonstrations. Iranians commonly hold a commemoration on the 40th day after a death. Anti-regime protests similarly erupted 40 days after security forces killed Neda Agha Soltan—a young Iranian protester—during the Green Movement in 2009. Security forces killed Agha Soltan on June 20, 2009, and the commemoration was on July 30, 2009.
