Mia Schem's mom said she didn't know her daughter was alive until she saw a Hamas hostage video. Mia Schem is one of about 200 people believed to have been abducted in Israel by Hamas fighters. Keren Schem explained that she did not know whether her daughter was dead or alive until she saw the video Hamas released. Meanwhile, an Israeli army spokesman called the hostage video of Mia Schem "psychological warfare," according to Reuters. As a result of the attacks by Hamas, Israel declared war, launching relentless retaliatory airstrikes in Gaza and killing more than 2,700 Palestinians, according to the Gaza Ministry of Health.
