Lauren Booth, the sister-in-law of former British Prime Minister Tony Blair, has caused widespread outrage after describing October 7 as a 'legendary day' for Muslims during an interview with Turkish media. Her remarks referenced the day of the Hamas attacks on Israel, which resulted in the deadliest massacre of Jewish people since the Holocaust, sparking condemnation from Jewish groups and counter-extremism experts. Booth, who converted to Islam in 2010, argued that the events had inspired millions to explore the Quran and praised the resilience of Gazans, but denied advocating violence against any group. The controversy has placed renewed scrutiny on Booth's past activism and created embarrassment for Tony Blair, who has been involved in efforts toward a Gaza peace deal.
